In that it uses an inequality sign (less then, greater than, less-than-or-equal, greater-than-or-equal) instead of an equality sign. When solving, special care must be taken - when multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality sign changes.

∙ 11y agoAn equation is a statement, such as 2+2=4, and an inequality is an equation that does not make sense, or one that isn't true, such as 2+2=5.
---------------------------------------------------
The person who answered above me is half right, half wrong. An inequality is actually NOT an equation that doesn't make sense or isn't true. An inequality has a variable in it. It's similar to an equation yet isn't exactly an equation. It compares numbers to each other. For example, a + 4 > 19. a + 4 > 19 is an inequality. They are different because an inequality doesn't have an equal sign so it can't be solved. An equation adds, subtracts, multiplies, or divides and it has an equal sign. Therefore, it can be solved. An example of an equation IS 2 + 2 = 4,14-12=2, 100/10=10, or 4x4=16.

What is the different between equation and inequality?
An equation is a mathematical that asserts theequality of two expressions. An inequality is a relation that holds between two values when they are different.
How does the solution to an equation compare to the solution to an inequality?
its different
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.
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.
How is graphing a linear inequality the same as graphing a liner equation?
They are alike in that you graph the lines in the same way, but they are different because you have to shade in one side of the line
Is 3x 114 an equation or an inequality?

How do you solve 3a square root 21?
There is no equation (nor inequality) so there is nothing to solve.There is no equation (nor inequality) so there is nothing to solve.There is no equation (nor inequality) so there is nothing to solve.There is no equation (nor inequality) so there is nothing to solve.
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.
The set of permissible replacement values for the variables in a particular equation or inequality is called the what for that equation or inequality?
It is called the DOMAIN!
How is an equation different from an inequality?
In an equation, what is to the left of the equals sign equals what is to the right. In an inequality, the left side is either less than, greater than, less than or equal to, or greater than or equal to the right side.
Is inequality in math is mean two different equation.yes or no?
No. You can solve an inequality in a similar way to an equation, but you end up with a range of answers (like X > 3) for each variable rather than set of exact answers (like X = 3)
Is a number an expression equation or inequality?
A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.
