X + y = 24....multiply by -3
3x + 5y = 100
---------------
-3x - 3y = - 72 (result of multiplying by -3)
3x + 5y = 100
--------------add
2y = 28
y = 28/2
y = 14
x + y = 24
x + 14 = 24
x = 24 - 14
x = 10
solution is (10,14)...and x represents 3 point q's and y represents 5 point q's......so this tells me there are 10 three point q's and 14 five point q's.

Answer: 1 Ticket
Step-by-step explanation:

I do this by moving the decimals 2 spaces back (Divide by 100)
5%=0.05
- Multiply the number of tickets sold by the new percentage number
20x0.05=1
