No, inequalities have more than, less then, at least, or no more than signs. Equations just have equal signs. An inequality answer can't be written as just a number it has to have a sign with it.

How would you prove that an inequality does have the same solution that an equation would have?

If you're given the inequality and the equation, then the way to prove that they have the same solution is to solve each one and show that the solutions are the same number. Don't strain yourself, though. An inequality and an equation never have the same solution.


If you replace the equal sign of an equation an put an inequality sign in its place is there ever a time when the same value will be a solution to both the equation and inequality?

Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.


What is the answer for -15 plus x100?

-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.


How does the solution to an equation compare to the solution to an inequality?

its different


What is the solution set for 2x2 plus 2x plus 1?

There can be no solution set because there is no equation nor an inequality - only an expression.There can be no solution set because there is no equation nor an inequality - only an expression.There can be no solution set because there is no equation nor an inequality - only an expression.There can be no solution set because there is no equation nor an inequality - only an expression.


How does the solution to an inequality differ from the solution to an equation?

The solution to an inequality generally is a region with one more dimension. If the inequality/equation is of the form x < a or x = a then the solution to the inequality is the 1 dimensional line segment while the solution to the equality is a point which has no dimensions. If the inequality/equation is in 2 dimensions, the solution to the inequality is an area whereas the solution to the equality is a 1-d line or curve. And so on, in higher dimensional spaces.


Why do we represent the solution to an inequality with a graph on a number line but we don't do the same for the solution to an equation?

An equation has an equal sign, which means that we know what the variable is equal to :)


When can you say that a number is called a solution in algebraic expression?

An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.


If you replace the equal sign of an equation and put an inequality sign in its place is there ever a time when the same value will be a solution to both the equation and inequality?

No - It will lead to a contradiction. No - It will lead to a contradiction.


How is a solution of an inequality like a solution of an equation?

X+9=17;8


Is there ever a time when the same value will be a solution for both the equation and the inequality?

Yes, but only when the inequality is not a strict inequality: thatis to say it is a "less than or equal to" or "more than or equal to" inequality. In such cases, the solution to the "or equal to" aspect will satisfy the corresponding inequality.


How is solving an inequality different from solving an equation?

In solving an inequality you generally use the same methods as for solving an equation. The main difference is that when you multiply or divide each side by a negative, you have to switch the direction of the inequality sign. The solution to an equation is often a single value, but the solution to an inequality is usually an infinite set of numbers, such as x>3.


Is 2 a solution of the inequality 2x 5 9?

2 is a solution of the equation, but not if it's an inequality.


What do you call a set with no solution?

A set would not normally have a solution. An equation or an inequality might.


Any value or values that make an equation or inequality true?

The solution.


What is the set of values for which an equation or inequality is true?

It is called the solution set.


What is a set of numbers that makes the equation or inequality true?

It is the solution set.


What is the solution or set for 617-h3-8?

There is no solution because there is no equation (or inequality); only an expression.


If you replace the equal sign of equation with inequality sign is there ever a time when the same value will be a solution to both the equation and the inequality?

No. You have written two quantities. They can't be equal to each other AND also UNequal to each other.


Is 5 a solution to 4x plus 7?

4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.


What is the solution to 30X to 29Y?

"30X to 29Y" is not an equation nor an inequality. There is, therefore, not a mathematical solution to the question.


What is the solution to x if 4x-62(2x-4)?

There can be no solution since there is no equation (nor inequality) in the question.


What is the solution to x - 9?

x - 9 is an expression, neither an equation not an inequality. An expression cannot have a solution.


What is the solution set for -x3-2x2-x-2?

There can be no solution set because there is no equation or inequality, only an expression.


What is solution to L plus U - M plus P?

There can be no solution because there is no equation (or inequality) but only an expression.
