What does y equal in 8x+y=15 and 9=2y+2x

y would equal to 3, while x would equal to 3/2 or 1 1/3.

Step-by-step explanation:

To solve this answer, use substitution.

Solve 8x + y = 15 for y.

Substitute - 8x + 15 for y in 9 = 2x + 2y.

Substitute 3/2 for x in y = - 8x + 15

When your done with that, your answer would be y = 3.

Hope this helps!

i believe that the answer is

b. y-1=-2(x-4)

hope this !
