still am not sure how to solve rational expression


x/[5(x+2)] + (x-3)/(x+2) = 7/5

  • math -

    Multiply both sides of the equation by (x+2) to get the x term out of the denominators. Then combine terms and use common denominators.
    (x/5) + (x-3) = (7/5)(x+2) = (7/5)x + 7/10
    (12/10)x - 28/10 = (14/10)x + 7/10
    (2/10)x = -35/10
    2x = -35
    x = -17 1/2
