Answer:
1/x+2/y=7/6
6(y+2x)=7xy
6y+12x=7xy
12x+6y=7xy (1)
3x+2y=2xy (2)
dividing both equations by xy
12x/xy+6y/xy=7xy/xy
3x/xy+2y/xy=2xy/xy
12/y+6/x=7
3/y+2/x=2
3 (12/y+6/x=7)
12 (3/y+2/x=2)
36/y+18/x=21 (3)
36/y+24/x=24
subtracting we get
-6/x=-3
x=--6/-3
x=2
put value of x (3) equation
36/y+18/2=21
36/y=21-9
36/y=12
y=36/12=3
y=3
x=2 & y=3 Answer
