Put = 1/x= a and 1/y= b
2a+2b/3= 1/6..............(1)
2a-b = 1............. (2)

Multiply the equation (2) by 4
8a-4b = 4............. (3)

Then solving the equation (1) and (2)
12a+4b= 1
8a-4b = 4
Adding them.
20a = 5
a = 1/4
Put the value of a in(2)
2×1/4-b = 1
b= -1/2


1/x= a
x= 4

1/y= b
y= -2.
