Hello, Malay!

I'm baffled . . . (more than usual)

Prove that the equations:

and

imply the equation:

I thought this would be simple (perhaps imaginative) algebra,

. . but I've made absolutely no progress.

Then it occured to me that I haveneverdone a problem like this.

Two equationsimplyanother? . . . Do I understand what that means?

(I don't think I do . . . )

I can find the intersections of the two graphs, but that's not the mission.

The first equation represents a pair of intersecting lines.

The second is a parabola (tipped 45°).

Somehow these twoimplythe hyperbola:

How does that work? .I haveno ideaof what I'm doing . . .
