Question

if 1/x+1/y=k and 1/x-1/y=k,then the value of y______.​

Answer 1

Step-by-step explanation:

Does not exist

Given equations are

x

1

+

y

1

=K --- (1)

and

x

1

−

y

1

=K --- (2)

Adding the equations, we get

x

2

=2K

⇒

x

1

=K

Substituting in eqn (1), we get K−

y

1

=K

⇒

y

1

=0

⇒y=

0

1

which is not defined or does not exist.
