Set the right-hand sides equal since both equal A:
3b + 8 = -9b - 4
Bring b-terms together: 3b + 9b = -4 - 8 → 12b = -12
So b = -1.
Then A = 3b + 8 = 3(-1) + 8 = 5 (check: -9(-1) - 4 = 9 - 4 = 5).
Solution: b = -1, A = 5.
3b + 8 = -9b - 4
Bring b-terms together: 3b + 9b = -4 - 8 → 12b = -12
So b = -1.
Then A = 3b + 8 = 3(-1) + 8 = 5 (check: -9(-1) - 4 = 9 - 4 = 5).
Solution: b = -1, A = 5.
