Case 1 : 4 b + 18 < = - 12 b - 14
4 b + 12 b < = -14 - 18
16 b < = -32
Divide both sides by 16, we have:
b < = -2 ( -3 , -4 , -5 ,................ )
Case 2 : -12 b - 14 < = 14 - 5 b
-12 b + 5 b <= 14 + 14
- 7 b < = 28
Divide both sides by 7, we have:
b >= -4 ( -3 , -2 , -1 , 0 , ........ )
From the combined solutions, we have seen that b = -3
