You must isolate the variable, for example:
If 3x + 5 = 14
you first subtract five from each side
3x + 5 = 14
- 5 - 5
which results in
3x = 9
you then divide both sides by 3
3x = 9
--- ---
3 3
so you are left with:
x = 3

How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
What number when substituded for the variable in an equation makes the equation true?
you have to solve the actual equation in order to answer this about your variable
How do you solve -12 is less than or equal to -12?
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.
Can you solve for a variable in an expression or equation?
you can only solve for one in an equation so it can equal something
Can you solve a variable with an equation?
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
When you find the value of a variable you solve or check an equation?
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
The process of finding the value of the variable that makes it a true equation is called?
solve
How doI solve system of equations by substitution?
Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.

Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
How do you solve the equation 720 equals 2a x 3b x 5c?
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
Can you solve for a variable in an expression or equation?

What should be added to both sides of this equation to solve for the variable a plus 39 equals -60?
-21
