Question

-11x - 72 = 84 + x
And I also need to do the check part

Answer 1

Explanation:

-11x - 72 = 84 + x

combine like terms on opposite side of =

(-11x )+ (-1x) = (84) + (72)

-12x = 156

divide both sides by -12 to isolate x

-12/-12 = 156/-12

x = -13

insert (-13) for x

(-11 * -13) -72 = 84 + (-13)

71 = 71

equality means its right
