    The number of hamburgers sold was 126.

    Step-by-step explanation:

    Let h = number of hamburgers sold

    let c = cheeseburgers sold

    c+h = 378

    c = 2h

    Substitute c = 2h into c+h = 278

    c+h = 378

    2h+h = 378

    Combine like terms

    3h = 378

    Divide by 3

    3h/3 = 378/3

    h = 126

    The number of hamburgers sold was 126.
