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?(:

  • Math -

    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 ?
