1. Download Wabbitemu
2. Go to y =
3. Insert equation under "Y1" ex: y1 = 5x - 8
4. Hit 2nd and then hit graph (or table)
5. Scroll through the columns until y1 and y2 have the same number
6. The number in your "x" column will be your x.
7. Continue on with the rest of the problem.
(Honestly I forgot how to do it by hand but hopefully you will learn how to use a graphing calc. I'd you don't know already!)
