Answer 2

solution.

Let 1/x= a & 1/y= b

then,, solving 1st.

2a+ 2b= 1/6

12 a+ 12b= 1.... (3)

now, solving 2nd.

3a+ 2b= 0....(4)
a= -2b/3

putting the value of a in 3,we get.

12(-2b/3)+ 12b= 1

=> -8b+ 12b= 1

=> 4b= 1

=> b= 1/4

Now, we have taken 1/y= 1/4 so,✔ y= 4.✔

now,putting the value of b in 4. we get.

3a+ 2 (1/4)= 0

=> 3a+ 1/2= 0

=> 6a+ 1=0

=> a= -1/6

now, we have taken 1/x= -1/6

so, ✔x= -6 ✔
