I took a quiz on Friday, and this one matrix problem really gave me a hard time. I'm going to try and recreate it...

{(1/1-4x)+(2/1-2y)=4

{(3/1-4x)-(4/1-2y)=7

The important things I remember from this question is that the denominator of both the X's was the same and the denominator of both the Y's was the same.

I honestly have no idea where to start this, even though I do really well with most 2-by-2's. I'm thinking I'm missing some simplification skills from an earlier class; if that turns out to be the case, moving this may be a good idea.
