    x = 3, y=0

    Step-by-step explanation:

    2x + y = 6

    y = x-3

    Substitute the second equation into the first

    2x + x-3 = 6

    Combine like terms

    3x-3 = 6

    Add 3 to each side

    3x-3+3 = 6+3

    3x = 9

    Divide each side by 3

    3x/3 = 9/3

    x = 3

    Now we need to find y

    y = x-3

    y = 3-3=0

    y=0
