3)
-z+7= -8
subtract 7 from each side to then get -z= -15
If you need a positive number for z multiply each side by -1

4)

(w)/(-9) +7=10

subtract 7 from each side to get
(w)/(-9) =10

Then multiply each side by -9 to get W= -90

5)
25=8+
(n)/(2)

first subtract 8 from each side to get 25=
(n)/(2)

Now multiply each side by 2 to get 50=n

6)

(y-8)/(3) =-7

first multiply each side by three to get y-8= -21
add 8 to each side y= -13

Hope I helped :)
