    Let a = adult tickets, s = student tickets. We are going to use these to set up a system of equations.

    a + s = 642

    a - s = 58

    Now we combine like terms. The s variables cancel out:

    2a = 700

    a = 350

    Now we plug back in.

    350 + s = 642

    Subtract 350 from both sides.

    s = 292

    There were 350 adult tickets sold and 292 student tickets sold.
