Question

What is the solution to the equation? 1 minus z/5=9 Answers: A.

z = 50   B. z = 44   C. z = –2   D. z = – 40

Answer 1

`1 - (z)/(5) = 9`

add
`(z)/(5)` to both sides.


`1 = 9 + (z)/(5)`

subtract 9 to both sides.


`-8 = (z)/(5)`

multiply 5 to both sides.


`-40 = z`

Your answer is D) z = -40
