    x = 15

    Step-by-step explanation:

    y = family members = 7

    x = cost of ticket

    7x + 6y = 147

    Substitute 7 for y:

    7x + 6 (7) = 147

    7x + 42 = 147

    Subtract 42 on both sides:

    7x + 42 = 147

    - 42 - 42

    7x = 105

    Divide both sides by 7:

    7x = 105

    x = 15
