x^2-2y^2=8

4x^2+12y^2=112

I need help I cannot figure out what to do with all the squared variables. I thought that I needed to use the elimination method but I may be wrong.

If this is part of the same take-home test, I again won't do the problem for you. Let me say, however, that I've done it by elimination and substitution, so both methods work. Look for example problems in your textbook to show you how to do it.
