2x/x-3 + 2/x = 3

I know I multiply both sides by x(x-3), but I don't know how to do that.

**Reiny**, Sunday, August 22, 2010 at 3:36pmrewrite the equation as ...

[2x/(x-3)](x(x-3)) + [2/x](x(x-3)) = 3(x(x-3))

notice in the first term, x-3 on top cancels x-3 at the bottom, in the second term x on top cancels x at the bottom , to get ...

2x(x) + 2(x-3) = 3x^2 - 9x

2x^2 + 2x - 6 = 3x^2 - 9x

x^2 - 11x + 6 = 0

x = (11 ± √97)/2
