Question

What is the solution to the equation?

1-z/5=9

A.
z = 50

B.
z = 44

C.
z = –2

D.
z = – 40

Answer 1

The answer would be D~ x = -40

Answer 2

1. -z/5=9+1 (subtract from both sides)
2.  -z/5=8 (simplify 9-1 to 8)
3. -z=8x5 (Multiply both sides by 5)
4. -z=40  (simplify 8x5 to 40)
5. z=-40 (Multiply both side by -1)
And your answer is -40 which is D
