Answer:

b=3 b=0

Explanation:

-8|4b-6|+9=-39

Subtract 9 from each side

-8|4b-6|+9-9=-39-9

-8 | 4b-6| = -48

Divide by -8

-8/-8 | 4b-6| = -48/-8

| 4b-6| = 6

When solving the absolute value, there is a positive and a negative solutions

4b-6 = 6 and 4b-6 = -6

Add 6 to each side

4b-6+6 =6+6 4b-6+6 = -6+6

4b =12 4b = 0

Divide by 4

4b/4 =12/4 4b/4 = 0/4

b=3 b=0
