  1. 23x29y=98(i)

    29x23y=110(ii)

    Adding (i) and (ii) we get ,
    52x52y=208
    52(xy)=208
    xy=4(iii)
    Substracting (ii) from (i),
    6x6y=12
    x+y=2(iv)
    Now by solving (iii) and (iv),
       2x=6
    x=3
    Substituting value of x in equation (iv),
    3+y=2
    y=1
    x=3 and y=1
