Solve. x+12/x+4 = x/x+8
A) x=4
B) x=8
C) x=6
D) x=6
thinking that it's B.. help?(:

I 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 ?
