    Let x = number of adult tickets
    and y = number of child tickets.

    Total tickets, x + y = 33 ....................(1)

    total money paid,

    8x + 5y = 201 ...................................(2)

    solve these two eqns and finish.

    First number = x

    other number = 2x - 3

    their sum,

    x + 2x - 3 = 330

    solve and finish.

    \frac{-1}{3}x + 7 = 16

    solve for x

    then in (2x + 1), substitute the value of x you found.
