**Reiny**, Monday, April 22, 2013 at 8:33pmI am sure you meant:

(x+12)/(x+4) = x/(x+8)

then

x^2 + 20x + 96 = x^2 + 4x

16x = -96

x = -6

If you meant it the way you typed it, it would turn into a quadratic equation, with 2 answers.

Since each choice contains only one answer, I assumed my interpretation.

Can you see how essential those brackets are ?
