# If, 1/x + 1/y = k and 1/x - 1/y = k, Then The Value Of Y _____.

Given:

$$\frac{1}{x} + \frac{1}{y} = k$$

And

$$\frac{1}{x} -\frac{1}{y} = k$$

Let

$$\frac{1}{x} + \frac{1}{y} = k — [1]$$

And

$$\frac{1}{x} – \frac{1}{y} = k — [2]$$

From the equation [1] and [2], we get

$$\frac{2}{y} = 0$$

Therefore, the value of y does not exist.
