Adult tickets sold = x

Children's tickets sold = y

x + y = 22

13x + 10 y = 277

Solve that pair of equations.

Hint: substitute 22-x for y in the second equation, and solve for x. .

The next step would be

13x + 220 - 10x = 277

3x = 277-220 = 57

Divide both sides by 3 and you have x.

You know how to get y after that.
