Answer:

y=5

Explanation:

8(y-7)= -16

(8)y-(8)7= -16

8y-56= -16

-16+56= 40

40/8= 5

y=5

(when you get y by itself)

hoped this helped a little bit.

Explanation:


\text{The distributive property:}\\\\a(b-c)=ab-ac\\\\8(y-7)=(8)(y)-(8)(7)=8y-56\\\\\text{If you want whole solution:}\\\\8(y-7)=-16\\8y-56=-16\qquad\text{add 56 to both sides}\\8y-56+56=-16+56\\8y=40\qquad\text{divide both sides by 8}\\(8y)/(8)=(40)/(8)\\\boxed{y=5}
