Crazy Simultaneous Equation ?!? 1. The problem statement, all variables and given/known data Solve for x and y 1)2x - 3y = 1 2)x2 - 2xy - 3y2 = -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.) 15y2 - 2y = 13 I then substituted the linear into eq3 and got a quadratic with only x in it: 4.) 5x2 - 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.
