Well, for that to be true, x has to be equal to three y squared. And of course, the xy pair has to also satisfy the equation for the curve. So why don't we use both of these constraints, and then we can solve for x and y. And so the easiest thing I can do, I can think of doing, is let's substitute x with three y squared, because they are the same. That's the second constraint. So if we take our original equation of the curve, we get y to the third minus, instead of writing x, I could write three y squared, three y squared times y, times y is equal to two. And so we get y to the third minus three y to the third is equal to two.
