Step-by-step 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
