    X=3y+5 (label equation 1)

    x-4y=3 (label equation 2)

    x=4y+3 (equation 2 rearranged, label equation 3)

    because equation 1 equals equation 3 let them equal each other

    3y+5=4y+3

    5=y+3

    y=2

    sub y=2 into equation 1

    x=3 (2) + 5

    x=11

    therefore the co-ordinates are (11,2)

    3y+5-4y=3

    5-y=3

    y=2

    x=3y+5

    x=11
