Explanation:

So

-4 * 3x = -12x

-4*1 = -4

Equation: -12x + -4 + x -3 = 15

move -12x and x to the other side, and 15 to the other/

Equation: -4+ (-3)-15 = 12x - x

simplified: -22=11x

x= -22 divided by 11

x= -2

Answer:

x = -2

Explanation:

-4(3x +1) = -12x - 4

-12x - 4 + x - 3 = 15

+4 +4

-12x + x - 3 = 19

-11x - 3 = 19

+3 +3

-11x = 22

22 / -11 = -2
