Answer: 7
Step-by-step explanation:
First, you would take 66 and subtract it from both sides. In return this would subtract it from 108 giving you 42. Then, you would divide both sides by 6 giving you a final answer of 7.
66 + 6b = 108
-66 -66
6b = 42
[tex]\frac{6b}{6} = \frac{42}{6}[/tex] = 7
Hope this helps.
