130/x + 180/ (x-5) = 5
make the denominator the same:
How do I find x once the problem is set up as 310x-650/x^2-5x?
oh my bad, I forgot the other part....
so [210x-650]/[x^2-5x]=5, 210x-650=5x^2-25x, 5x^2-235x+650=0, x^2-47x+130=0, using quadratic formula, we get x=0.5(47-sqrt1689), x=0.5(47+sqrt1689)
hope it helps, thanks!
