I don't know, but do you just substitute in y and solve?
Thanks for the help!^^

Put x^2 = y - 4 in the first equation and solve the quadratics for y.
oops. my mistake. the equations were:
Square the second equation to get: (2x-3)^2. Substitute that into the first equation. Solve for x. Plug the value you found for x back into equation 2, that gives you y.
