    Answer is B. (4,0)

    Step-by-step explanation:

    2x - y = 8

    x + y = 4

    solve the equation

    2x - y = 8

    y = 4 - x

    substitute the value of y into the equation

    2x - (4 - x) = 8

    solve the equation

    x = 4

    substitute the value of x into an equation

    y = 4 - 4

    solve the equation

    y = 0

    answer is (4,0)
