Answer:
reply me whether the answer was right or not
Step-by-step explanation:
Let 1 ÷x+y be p and 1÷x-y be q
So, 3p + 2q =2--------eq(1)
And 9p -4q=1---------eq(2)
Now multiply eq(1) by 3
Then it become
9p+6q=6--------eq(3)
Now subtract eq(2) from eq(3)
9p +6q=6
9p-4q=1
(-). (+). (-)
________
10q=5
q=1/2-----eq(4)
Put the value of q in eq(2)
Then p=1/3
__1___ =p.
x+y.
__1___ =1/3
x+y
x+y=3------eq(5)
__1___ =q
x-y
__1___ =1/2
x-y
x-y=2-------eq(6)
By adding eq(4) and eq(6)
We get, 2x=5
X=5/2
And y=1/2
Therefore, X=5/2 &y=1/2
