Answer:

B. Add 5y to both sides in the first equation.

Step-by-step explanation:

When we add 5y to both side in the first equation we will see that x = 22 + 5y

Then we can use this information in second equation like this:

-8(22+5y) + 7y = 22 which is a simpler equation and easier to solve.

So the answer to this question is B.
