No, you can only simplify an expression. To solve for a variable, it must be in an equation.
isolate the variable
Equations are used to find the solution to the unknown variable.
You normally "solve" something when there is a variable involved. In this case there is no variable. All you have to do is decide whether it is true or false. If this is derived from an original equation (or, in this case, inequality) which involved variables, then if the equation (or inequality) without variables is true, it means it is true for ANY value of the variable. If it is false, the original equation (or inequality) can't be satisfied by any value of the variable.
An expression cannot be solved; an equation or an inequality may be.
Identify your variables. Make one of the variables equal zero and solve for the other variable. Once you have a solution for this varaible this solution is called a zero. Make the other variable equal to zero and solve for the other variable. Once you have a solution for this variable this solution is also called a zero.
There is no equation (nor inequality) in the question. There is also no unknown variable. So there is nothing to solve.
In the case of an inequality, if you mulitply by a negative number, you have to reverse the direction of the inequality. E.g.: -x < 10 becomes: x > -10 (Here, I multiplied by -1, and simultaneously reversed the direction of the inequality.)
Multi-step inequalities can be solved in the same manner as multi-step equations.Follow these steps in solving a multi-step inequality: Remove all grouping symbols.Combine like terms on each side of the inequality.Use the addition property of inequality to get the variable term on one side and constant on the other.Use the multiplication property of inequality to make the coefficient on the variable 1.Check your answer.It is impossible to check every answer of an inequality because the solution set is infinite, but you can test some of the elements in the solution set.
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.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
There can be no solution because there is just an expression - no equation nor inequality.
You cannot. 3x + 4 is an expression, not an equation or inequality. There cannot be a solution.
each of the four regions created on the coordinate plane by the x- and y-axes.
I don't see any numbers below.One method to solve this is to replace each of the numbers in the inequality, do the calculations, and then check whether the inequality is satisfied. Another method is to get the general solution for the inequality, then check with each of the numbers.
This is not an inequality. There is no <,>, or = sign.
An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal". Assuming one of these inequality signs is between the "4x" and the "12", for example: 4x < 12, just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.
Just add 25 to both sides of the inequality - that way, you will isolate the "x", i.e., solve for "x".
Through signs of inequality Solve each inequality Graph the solution? 2(m-3)+7<21 4(n-2)-6>18 9(x+2)>9(-3)
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
The question contains an expression, not an equation nor inequality. An expression cannot have a solution.
Pressumably you want to solve for "a". Divide both sides of the inequality by 3. That will give you the solution.
Nothing will solve an expression. You need an equation (an equality or an inequality) beofre a solution of any kind is possible. Tha means you need something on both sides of the equality (or inequality) sign.
If the solution contains one variable which has not been fixed then there are infinitely many solution.
