You could solve this one of a couple of ways.  Either by using matrices (which I don't recommend for this), substitution, or addition.  Probably the substitution method is the easiest. Are you familiar with either one of those (substitution or addition methods)?

yes, ive just done a few lessons on substitution. and i think ive heard of addition methods.

Let's do substitution then.  We need to solve the second equation for x, just to make it easiest.  Can you solve that second equation for x?  x - 7y = -7
