解

The numbers : 48 - \frac{97 - 9049}{4}, \frac{97 - 9049}{4} or 48 - \frac{97 + 9049}{4}, \frac{97 + 9049}{4}

解答ステップ

Represent the numbers with

x and y

:

number 1 : x

number 2 : y

A.T.Q.:

x + y = 48

x = 3 + 2 y x

x + y = 48, x = 3 + 2 y x : (x = 48 - \frac{97 - 9049}{4}, y = \frac{97 - 9049}{4} x = 48 - \frac{97 + 9049}{4}, y = \frac{97 + 9049}{4})

The numbers : 48 - \frac{97 - 9049}{4}, \frac{97 - 9049}{4} or 48 - \frac{97 + 9049}{4}, \frac{97 + 9049}{4}
