Don't quote that unless you have the tentacles to back you up.

Sure is a monster!

I'd start like this:

a = 2x^2 - y^2 + 2y
b = x^2 + y - 5
c = 3x^2 - 6y + 13

Then play with these:

x^3 - y^3 + 15x - 3a = 10
3sqrt(y) + sqrt(b) - sqrt(c) = 0

Then substitute back in...I don't even wanna think about it !!

Just to "see", entered those 2 equations at Wolfram:

Wolfram|Alpha: Computational Knowledge Engine

Now continue, doing the substitution...
