What is the solution of the equation? 5x – 31 = 2x + 8 x = _________

OpenStudy (aripotta):

so you wanna get x by itself. what should we do first?

OpenStudy (anonymous):

divide

OpenStudy (aripotta):

no, you wanna add 31 to both sides first. once you do that, you get 5x = 2x + 39

OpenStudy (aripotta):

now you subtract 2x from both sides 3x = 39 and now you can divide both sides by 3 x = 13
