Question

Could use some help.
z/7−9=2
Two-Step Equations and Properties of Equality

Answer 1

So for this one, you have to isolate the variable first which means that you would have to add 9 to both sides resulting in:
z/7=2+9
then simplify.
z/7=11
The last step is to multiply both sides by 7.
(7)z/7=11(7)
Simplify.
z=77
If you have any questions don’t be afraid to comment.
Hope I helped :)

Answer 2

z = 77

Explanation:

Given

`(z)/(7)` - 9 = 2 ( add 9 to both sides )

`(z)/(7)` = 11 ( multiply both sides by 7 to clear the fraction )

z = 77
