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

$b\ge \:5$
