Question

The product of two numbers x and y is twice the sum of the numbers. What is the sum of the reciprocals of x and y?

Answer 1

Step-by-step explanation:

xy = 2(x+y)

1/x+1/y=x+y/xy=2

Answer 2

Answer:

0.5

Step-by-step explanation:

when we add the reciprocals, we get (x+y)÷xy, substitute xy=2(x+y), thus we get 1/2, 0.5
