Ayyy, wassup people! can y'all do my homework? Imma reward you.

1. Simplify Fully
2.Write as a single fraction in it's simplest form.

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)
