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
