Question

The integers X and Y fulfil the condition 2X=5Y. Which can be considered for X+Y?

Answer 1

X + Y could equal to
`1 (2)/(5)X` or
`3 (1)/(2)Y`.

Explanation:

2X = 5Y

Y =
`(2)/(5)X`

X =
`(5)/(2)Y`

Hence, X + Y could equal to X +
`(2)/(5)X` =
`1 (2)/(5)X` or Y +
`(5)/(2)Y` =
`3 (1)/(2)Y`.

Hence, X + Y could equal to
`1 (2)/(5)X` or
`3 (1)/(2)Y`.
