plss mark me brainliest I know this answer I will tell you in comment

Step-by-step explanation:

1.

-1 + 2x = 9

to get the solution

2x = 10

x = 5

2.

4 = 8 - x

x = 8 - 4 = 4

x/4 = 1

we could also write this

4 = 8 - x | /4

1 = 2 - x/4

x/4 = 1

x = 4

3.

x/2 - 3 = -5

to solve

x/2 = -2

x = -4

i believe it is c.y = 9x
