Answer:

x = -10

Step-by-step explanation:

combine like terms

3-3x=13-2x

since there are 2 x's move one them

3-3x = 13 -2x

 +2x        +2x

--------------------

3 - x = 13

-3        -3

-------------

-x = 10

you cant have negative variables so we multipy both sides by -1

-1(-x = 10)

x = -10
