    Answer:

    We have,

    2x+3y=9 ……. (1)

    3x+4y=5 …… (2)

    Now,

    y= 9−2x/3

    On putting the value of y, in equation (2), we get

    3x+4( 3 −2x)=5

    3x+ 336−8x=5

    9x+36−8x=15

    x=15−36

    Now, put the value of x in equation (1), we get

    y=

    3

    9−2(−21)

    y=

    3

    9+42

    y=

    3

    51

    =17
