when you add these 2 equations the terms in y disappear to give 5x^2 = 2 solve for x (there will be 2 solutions) and plug these into one of the original equations to find the values of y.

ok to do this you multiply equation 1 by 2 and equation 2 by 3 to give 4x^2  6y^2 = 38 9x^2 + 6y^2 = 90 is that = 30 in second equation?
