    3x+y=6

    x+y=2

    rewrite x + y = 2 as y = 2-x

    Replace Y in the first equation with the re-written equation:

    3x + 2-x = 6

    Solve for x:

    3x + 2-x = 6

    subtract x:

    2x + 2 = 6

    Subtract 2 from each side:

    2x = 4

    Divide both sides by 2:

    x = 2

    Now you have x, replace x with 2 in the second equation and solve for y:

    x + y = 2

    2 + y = 2

    Subtract y 2 from each side:

    y = 0

    The answer is: X = 2, Y = 0
