Can someone please tell me how to solve this problem? Trying to help a teen who is staying with me with their homework, but I am clueless.

Oops....sorry, I forgot to put the problem in.
-2y = 228 + 8x
10x + 11y = -64
Solve each system of equations using the substitution method.

Put them in standard form:
Elminate a variable. I will pick x. Multiply the top equation by 10, the second equation by 8
now subtract the second equation from the first..
and proceed to solve for y. Then, substitue back in the original equation, either one, and solve for x.
