4 (4x - 3) = -76 Explain you solution process

4 (4x - 3) = -76

mutiply the bracket by 4

(4) (4x) = 16x

(4) (-3) = - 12

16x-12 = - 76

move - 12 to the other side

sign changes from - 12 to + 12

16x-12+12 = - 76+12

16x=-76+12

16x = - 64

divide both sides by 16 to get x by itself

16x/16 = - 64/16

Cross out 16 and 16, divide by 16 and then becomes 1*1*x = x

x=-64/16

Answer: x=-4
