Answer: £5 = 52 tickets, £8 = 23 tickets

Step-by-step explanation:

Quantity Cost

£5 Tickets x 5x

£8 Tickets y 8y

TOTAL 75 444

Cost: 5x + 8y = 444 → 1(5x + 8y = 444) → 5x + 8y = 444

Quantity: x + y = 75 → -5( x + y = 75) → -5x - 5y = -375

3y = 69

y = 23

Input y = 23 into one of the original equations to solve for x:

x + y = 75

x + 23 = 75

x = 52
