Answer:

b = -7

Explanation:


2(b+5) = 3(b-2) + 23

for the left side of the equation:
2*b + 2*5 = 2b + 10

for the right side of the equation:
3*b + 3*-2 = 3b - 6 + 23 = 3b + 17


2b + 10 = 3b + 17

to isolate b, subtract 2b from both sides


10 = b + 17

subtract 17 from both sides


-7 = b\\b = -7
