Answer:
The 2 tickets will cost £44.10 after the increase.
Step-by-step explanation:
First, you have to multiply £19.60 by 12.5% to find the increase in the cost of tickets.

Add the price increase to the original cost to find the new cost of each ticket.

Multiply the result by 2 since you have to look for the cost of the 2 tickets.

20x - 15 - 3x - 1 = 15x + 27 + 2x
17x - 16 = 17x + 27
17x - 17x = 27 + 16
0 = 43
Since zero is not equal to 43, this equation has no solution.
Haha this one is the exactly why
