    Let's say adult tickets = x and student tickets = y

    (1) x + y = 429

    The number of student tickets sold is twice the number of adults tickets sold, therefor y = 2x

    Now if we substitute this into equation (1), we get:

    x + 2x = 429

    3x = 429

    x = 143

    Therefor the number of adult tickets sold is 143
