Plug them into x and y to get:

4A + B = 7

and

-5A + -3B = 7

And solve

4A + B = 7

and

-5A + -3B = 7

And solve

oh... sorry, just finished a semester in Linear Algebra :-)

but really... you have 2 equations that are equal to each other ad 2 unknowns... that is easy to solve just read the math book you have (I know, I know who reads a math book :-D )
