Answer:


b\ge \:5

Explanation:


-138\ge \:-6\left(6b-7\right)\\\\

Switch sides


-6\left(6b-7\right)\le \:-138\\

Multiply both sides by -1


\left(-6\left(6b-7\right)\right)\left(-1\right)\ge \left(-138\right)\left(-1\right)

Simplify


6\left(6b-7\right)\ge \:138

Divide both sides by 6


(6\left(6b-7\right))/(6)\ge (138)/(6)

Simplify


6b-7\ge \:23

Add 7 to both sides


6b-7+7\ge \:23+7

Simplify


6b\ge \:30

Divide both sides by 6


(6b)/(6)\ge (30)/(6)

Simplify


b\ge \:5
