i don't know this question but i have made it by photomath app.
you can get it from playstore
-138 <span>≥ -6(6b - 7)
Start by multiplying everything within the parentheses by -6.
-138 </span><span>≥ -36b + 42
Now move the +42 to the other side, so you're left with -36b. (You do this by subtracting 4242)
-138 - 42 </span><span>≥ -36b
-180 </span>≥ -36b
Divide both sides by -36 to find the value of b.
-180 / -36 ≥ b
5 ≥ b.
The answer is b ≤ 5.
