Solve:

6X+2=9x-7

Answer 5

!!WARINING THERE WILL BE NO EXPLANAITION IF YOU NEED HELP GO TO SOLVING ONE STEP AND TWO STEP EQUATIONS!!

(1) Reerange equation so all the unkowns are on one sode
(2) Numbers on other side
(3) Solve for unknown using inverse operation

There is always a cooeficient for a variable for example: for X (1X)

3=X
