Question

Please help!!! I do not understand. Just the top one.

Answer 1

z/8-5=-3
So what you would do first is get rid of -5 so you'd add 5 to both sides~
z/8-5+5=-3+5
z/8=2
Now, you'd multiply 8 on both sides
z/8*8=2*8
z=16

Answer 2

z/8-5=-3 add 5 to both sides

z/8=2 multiply both sides by 8

z=16
