Let a be the number of tickets Alan hands out and m be the number Marcy hands out. We know that a + m = 150 and m = 5a - 6
Substituting the second equation into the first, we get a + 5a - 6 = 150
Adding 2 to both sides, we get a + 5a = 156
Combining like terms, we get 6a = 156
Dividing both sides by 6, we get a = 26
