Answer 1

-2(5-4)=4(6+12)

-10+8=24+48

-2=72

=-36

Answer 2

Explanation:

-2(x - 4) = 3(x + 12) {Use distributive rule}

-2*x - 4 *(-2) = 3*x + 12*3

-2x + 8 = 3x + 36 {add 2x to both sides}

8 = 3x + 36 +2x

8 = 5x + 36

8 - 36 = 5x {subtract 36 from both sides}

-28 = 5x

5x = -28 {Divide both sides by 5}

x = -28/5

x = -5.6
