    5x+6y=50

    -x+6y=26

    Make the second problem and multiply everything by - 1

    5x+6y=50

    -1 (-x+6y=26)

    X-6y=-26

    Eliminate the y and combine evrything

    6x=24

    Divide 6 both sides

    X=4

    Then substitute the x

    - (4) + 6y=50

    -4+6y=50

    Add 4 both sides

    6y=54

    Divide 6 and y=9 x=4
