1. 2(H-8)-h=h-16
podryga [215]

(1) C and (2) D

(1)

distribute the left side of the equation

2h - 16 - h = h - 16 ( simplify left side )

h - 16 = h - 16

Since both sides are equal, any value of h will make the equation true.

Hence there are infinitely many solutions to the equation → C

(2)

3 + 6z = 13 + 6z ( subtract 6z from both sides )

3 = 13 ← not possible

Hence there are no solutions to the equation → D
