    Answer:

    x=1/2 and y=1/3

    Step-by-step explanation:

    2/x + 3/y =13. eqn.(1)

    5/x + 4y =-2. eqn.(2)

    2y+3x =13xy. eqn.(3)

    5y-4x =-2xy. eqn.(4)

    add eqn.(1) and (2)

    8y+12x+15y-12x =52xy-6xy

    23y=46xy

    x= 1/2

    put the values of x in eqn(3)

    2y+3/2 =13y/2

    4y+3=13y

    9y=3

    y=1/3
