Answer 6

q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6q + 36 = 42.6
