Then solve like you'd solve a regular equation. Finally, you must check all answers because squaring equations may introduce extraneous solutions.

"you must check all answers because squaring equations may introduce extraneous solutions." particularly important... and it's good to check your work in this manner, even when extraneous solutions aren't possible.
