Answer:

C. 1/2

There are many ways to do this but I'll use substitution.

Step-by-step explanation:

Bottom equation yields x = 4 - 8y

plug that into the top equation results in:

4(4 - 8y) - y = 3y + 7

Simplify this to find y:

-36y = -9

y = 1/4

Plug that into the bottom equation we get:

x = 4 - 2 = 2

Thus, xy = 2(1/4) = 1/2 (C)
