Answer 1

Answer:

X = 1 or 2

Step-by-step explanation:

First you make the denominators the same, multiplying the first by (x-7) and the second by (x+4) which gives you (x-7) - (x + 4) /(x+4)(x-7). you need to simplify the top to x -x -7 -4 = -11. since the the right side is +11/30, you are looking for a -30 on the bottom. so x^2 - 3x - 28 = -30 which simplifies to x^2 - 3x + 2. This factors to (x - 2) (x - 1), so x = 2 or 1. plug both into (x-7) - (x + 4) /(x+4)(x-7) and you get for 1: -11/ (5)(-6) and for 2: -11/ (6)(-5)
