You have 2 different expressions for y. So if both of those things are =y, then they are also equal one another. So set the expressions =, then solve for x. The x^2 terms will conveniently go away, and you will have a simple linear equation in x to solve. Once you have solved that, you will know the value of x. Then you can just substitute that value back into either of the equations to find y.
