    Answer:

    x+y=14

    x+y=4

    2y=10

    y=10/2=5

    x+y=14

    x+5=14

    x=14-5=9

    Answer:

    the values of x and y are 9 and 5 respectively.

    Step-by-step explanation:

    given equations are x+y=14....(1)

    xy=4 => x= 4+y.....(2)

    now, substituting equation (2) on equation(1)

    (4+y)+y =14

    => 4+2y = 14

    => 2y = 144=10

    =>y= 10/2 = 5....(3)

    now, substituting the equation (3) on equation (2)

    x= 4+y

    => x= 4+ 5 = 9

    hope it will help you
