b=3 b=0
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
