Answer is -10
Work: -(5+5)
Given:

To find:
The simplified expression by factoring.
Solution:
Let us factor the numerator:

31x can be written as 3x + 28x.

Take 3x common in 1st two terms and 7 common in next two terms.

Make sure the remaining terms in the both brackets must be same.
Now, take out common factor (4x + 1).

In the same way, factorize the denominator:

8x can be written as 4x + 4x.

Take 4x common in 1st two terms and 1 common in next two terms.

Make sure the remaining terms in the both brackets must be same.
Now, take out common factor (4x + 1).

Substitute the terms we found for numerator and denominator:

Cancel the common factors.

The simplified expression is
.

Answer:
d. x= -3
Step-by-step explanation:
3(x+4) = 3
x+4= 3-3
x+4= 1
x= 1-4
x=-3
