Answer: x = (z+8h)/8
This is equivalent to x = z/8 + h or x = (1/8)z + h
=================================================
Work Shown:
z = 8(x-h)
z = 8x-8h ... distribute
8x-8h = z
8x = z+8h .... adding 8h to both sides
x = (z+8h)/8 .... dividing both sides by 8
x = z/8 + 8h/8
x = z/8 + h
x = (1/8)z + h
