Answer:


\boxed {x = -1}

Explanation:

Solve for the value of
x:


15 + 3x = 3(2 - 2x)

-Use Distributive Property:


15 + 3x = 3(2 - 2x)


15 + 3x = 6 - 6x

-Take
6x and add it to
3x:


15 + 3x + 6x = 6 + 6x - 6x


15 + 9x = 6

-Subtract both sides by
15:


15 - 15 + 9x = 6 - 15


9x = -9

-Divide both sides by
9:


(9x)/(9) = (-9)/(9)


\boxed {x = -1}

Therefore, the value of
x is
-1.
