    Step-by-step explanation:

    2x+4y=36 - equation 1

    6x+2y=3 - equation 2

    from equation 1,

    2x + 4y = 36

    2x = 36 - 4y

    x = 36/2 - 4y/2

    x = 18 - 2y - equation 3

    insert equation 3 into equation 2

    then, 6x+2y=3

    therefore, 6 (18 - 2y) + 2y = 3

    108 - 12y + 2y = 3

    108 - 10y = 3

    108 - 3 = 10y

    105 = 10y

    y = 105/10

    y = 10.5

    in solving for x, insert y = 10.5 into equation 1

    therefore, 2x+4y=36

    2x + 4 (10.5) = 36

    2x + 42 = 36

    2x = 36 - 42

    2x = - 6

    x = - 6/2

    therefore x = - 3

    Ordered pair, x = - 3 and y = 10.5
