3x+7=x - 15 i dont know how to solve it
the answer is -11 but i dont know how to get to that

3x + 7 = x - 15

First, make sure to subtract  from both sides.

Second, simplify 3x - x to get 2x, and then keep the 7.

Third, subtract  from both sides. 

Fourth, simplify -15 - 7 to get -22.

Fifth, take the 2 and divide both sides by it, keeping the  by itself.

Sixth, since 11 goes into 2 to get 22, simplify the fraction to 11.


 x = -11
