1. The problem statement, all variables and given/known data

Solve for x and y

1)2x - 3y = 1

2)x^{2}- 2xy - 3y^{2}= -3

2. Relevant equations

3. The attempt at a solution

I substituted the linear equation into the quadratic and got a quadratic with only y in it:

3.)15y^{2}- 2y = 13

I then substituted the linear into eq3 and got a quadratic with only x in it:

4.)5x^{2}- 6x = 9

Do I need substitute that linear into these quadratics twice more so I get 2 simultaneous quadratics with only x in them and 2 quadratics with only y in them?

I've been on this question for about half an hour now but this is a sample question from a test so theres no way I could spend that long on a single question on a test. I must be doing it wrong.
