do I just plug in the 2nd equation into the first?

kinggeorge · Answer

have you seen solutions posted in a similar fashion to these?$$\left\{ x, y \in R: x, y > 0 \right\}$$$$\left\{x, y \in R: x \geq 5, y < 0 \right\}$$

kinggeorge · Answer

That's what set-builder notation looks like.

kinggeorge · Answer

As for solving the equation itself, plugging the 2nd equation into the first should work.
