Answer 2

1/x + 1/y = 20/3

The two equations are:

1) 1/x + 2/y = 20

2) 3/x + 3/y = 20

If we look at the second equation closely, we can say that if three is multiplied to (1/x + 1/y), we get 3/x + 3/y

So, 3/x + 3/y = 20

⇒ 3 [1/x + 1/y] = 20

⇒ [1/x + 1/y] = 20/3.

So, 20/3 is the required answer.
