2/x+1 = 14( add both)
x+1)/2 = 1/14
x+1 = 1/7
x= -6/7
1/x+1 + 1/y+1 = 10
7 + 1/y+1= 10
1/y+1= 3
y+1 = 1/3
y= -2/3

= 4
Let,
So, replacing the value we get,
=> 1(a) + 1(b) = 10 -------->[1]
=> 1(a) - 1(b) = 4 -------->[2]
Now, [1] + [2]
=> a + b + a - b = 10 + 4
=> 2a = 14
=> a = 7
Now, putting the value of 'a' in equation [1] we get,
=> a + b = 10
=> 7 + b = 10
=> b = 10 - 7
=> b = 3
So we got the value of 'a' and 'b
Now, as we have taken earlier
so by putting the value of 'a' and 'b' we get,
and
Hence , the value is
