**Anonymous**, Wednesday, March 27, 2013 at 5:01pm9(x+3)-3(x+3)=2

9x+27+3-9=2

6x-36

6x=48

x=8

Is this right?

**Wayne**, Thursday, March 28, 2013 at 9:36amI apologize! I misread your equation. Multiply through by x^2 gives:

9x^2-8x-2=0. Use Quadratic Formula to get two solutions: (8+sqrt(136))/18 and (8-sqrt(136))/18. I checked, and both work!
