Pre-Calc

posted by Josh

Please help me with this problem-I'm stuck
(x-2)/(x+2) = (x+10)/x

I'm not even sure where to start-Thanks for any help you can provide

  1. Reiny

    just cross-multiply
    x(x-2) = (x+2)(x+10)
    x^2 - 2x = x^2 + 12x + 20
    -14x = 20
    x = -20/14
    x = -10/7

    That is so easy-I can't believe I was screwing it up so badly-Thank you
