x = ___

Answer 1

THE THING IM ABOUT TO TELL YOU IS SOMETHING THAT SOME PEOPLE IN PRECALCULUS STILL DON'T UNDERSTAND!

The solution of a SINGLE equation is where it touches the X-AXIS.

The solution of TWO equations are where they touch EACH OTHER.

Now to graph them...
The point at which they touch is their solution, therefore (2,3) is their solution.

Best of luck!!
