Question 242071
Do you 3x + 20 = 5x - 6?

Do you mean something like that?

Simply combine like terms and then simplify.

Put the x terms with the x terms and the constants with the constants and then simplify.  Don't forget to CHANGE THE SIGNS of the x terms and constants when crossing the equal sign.

Understand?

Take my example: Solve for x.

The words "Solve for x" means to find the value of x. 

3x + 20 = 5x - 6

3x - 5x = -20 - 6

-2x = -26

x = -26/-2

x = 13
