6/x-3/y=10
in LHS take LCM as xy and then transpose xy to RHS
6y-3x=10xy.This is eq1
2/x-5/y=6
in LHS take LCM as xy and then transpose xy to RHS
2y-5x=6xy.This is eq 2
Do eq1-3eq2
In LHS 6y-3x-6y+15x
=12x
in RHS
10xy-18xy
=-8xy
12x=-8xy
y=-3/2
Put y=-3/2 in eq 1
-9-3x=-15x
x=3/4
1/x-1/y
=y-x/xy
=(-3/2-3/4)/(-3/2*3/4)
=-9/8*-8/9
=1
