Question

2/x + 2/y = 20 , 3/x + 3/y = 20 , 1/x + 1/y = ?​

Answer 1

Step-by-step explanation:

2/x + 2/y = 20

or 2(1/x +1/y)= 20

or 1/x +1/y = 10

3/x +3/y = 20

or 1/x +1/y = 20/3

Answer 2

Given:

2/x + 2/y = 20 , 3/x + 3/y = 20

To find:

1/x + 1/y = ?​

Solution:

From the given information, we have the data as follows.

The set of equations.

2/x + 2/y = 20 , 3/x + 3/y = 20

Consider the first equation.

2/x + 2/y = 20

2[ 1/x + 1/y] = 20

1/x + 1/y = 10 ...... (1)

Consider the second equation.

3/x + 3/y = 20

3[ 1/x + 1/y] = 20

1/x + 1/y = 20/3 ...... (2)

Compare the equations (1) and (2).

The same set of parameters cannot have the different values.

Therefore, no solution for the equation 1/x + 1/y.
