Answer:
(x+4)(x-5)
Step-by-step explanation:
We can look at it by thinking of two numbers, that add up to -1 and multiply to -20. We can first do this by looking at factors of -20, which are 1, -20, -1, 20, 2, -10, -2, 10, and so on. After looking through it, we can notice that -5 and 4 added equal -1, and when multiplied equal to -20, so they work. So, we factor to (x+4)(x-5)

Like a first step bc. there is a denominator this will be more usefully eliminate it so what you can make it multiplied both sides by 2
- so will get
-2/2x +2*3/2 = 2(-4x+7)/2
(-2x +6)/2 = 2(-4x+7)/2 common denominator the 2 so make the numerators equal and solve for x
-2x+6=-8x+14
6x=8
hope helped
