    2x+5y=34 ... (1)

    x+2y=14

    x=14-2y ... (2)

    substitute value of x from (2) in (1)

    2 (14-2y) + 5y=34

    distribute 2 over the bracket

    28-4y+5y=34

    28+y=34

    y=34-28

    y=6

    plugging this y in second equation to get x

    x=14-2y

    x=14-2 (6)

    x=2

    answer x=2, y=6
