Select three equations that have no solution.
A.19 + b + 12b – 8 – 5b = 2b – 7 + 3b + 3b – 4

B.4b – 9b – 13 – 6 + 16b = 1 – 8 + 6b + 5b – 12

C.7 + 7b – 2 – 15b + b = 4b – 5 – 11b + 2 + 10

D.10b + 8b + 9 – 18b + 3 = 5 + 6b – 2b – 12 + 7

E.9 – 19b – 9 – 2b + 7b = 4b + 3 + 14 – 4b – 17

F.8b – 10 + b + 3b + 2 = 7 + 2b + 10b – 18 – 3
