    Answer:

    1) (7x-11)/12

    2) (3x+4)/(x²-16)

    Step-by-step explanation:

    1)

    (x+3)/4 + (x-5)/3

    Lcm: 12

    [3(x+3) + 4(x-5)]/12

    (3x+4x+9-20)/12

    (7x-11)/12

    2) 1/(x+4) + 2/(x-4)

    Lcm: (x+4)(x-4) = x²-16

    [(x-4)(1) + (x+4)(2)]/(x²-16)

    (x-4+2x+8)/(x²-16)

    (3x+4)/(x²-16)

    Answer and Step-by-step explanation:

    Good~Day!

    Let's~answer~your~question~shall~we?

    Answer for the first question:

    =\frac{3(x+3)}{12} +\frac{4(x-5)}{12}

    =\frac{x(x+3)~+~4(x-5)}{12}

    =\frac{3x+~9+~4x~4-20}{12}

    =\frac{7x~-~11}{12}

    Answer:

    →  \frac{7x~-~11}{12}

     ________________________________________________

    Answer for the second question:

    \frac{x-4}{(x+4)~(x-4)} ~+ ~\frac{2(x+4)}{(x+4)~(x-4)}

    =\frac{x-4~+~2~(x+4)}{(x+4)~(x-4)} =\frac{x-4~+~2x~+8}{(x+4)~(x-4)}

    =\frac{3x~+~4}{(x+4)~(x-4)}

    Answer:

    →  \frac{3x~+~4}{(x+4)~(x-4)}
