I'm an Algebra 2 student and we are learning parametric equations. I am having difficulty solving this one, although I'm good on most of the others.

Here it is:

y = 2t

x = t^2 + 2t

The trouble I'm having is coming up with a "y=" equation, because the y term becomes quadratic. What I have gotten down to is: y^2 = 4x - 4y. Where do I go from here? Thanks...
