Now that I have x in terms of y, I'm going to plug that x value into the OTHER equation:
So now we have an equation with just one variable. This should be easy to solve if we're careful with distribution and minus signs:
Alrighty, we have a y value. Now we want the x value. If only we had x written down in terms of y someplace .. oh hey, peek up at the *** above:
So our solution may be (4, -2).
Let's check just to make certain we're correct:
We've got it. And more importantly, we know we are right because of our check.
