Simplify:

2/x+5 + 4/x+3 times (x+3)(x+5)/(3x+13)

  • Algebra -

    I believe you mean (2/(x+5) + 4/(x+3))*(x+3)(x+5)/(3x+13)

    Distribute the (x+3)(x+5)/(3x+13)

    2(x+3)/(3x+13)+4(x+5)/(3x+13)

    They have the same denominator, so you can add them:
    (2(x+3)+4(x+5))/(3x+13)

    Simplify the numerator:
    (2x+6+4x+20)/(3x+13)
    (6x+26)/(3x+13)

    Divide by (3x+13):
    2(3x+13)/(3x+13) = 2
