The numbers : - 14 \frac{1}{2}, - 19 \frac{1}{2}

解答ステップ

Represent the numbers with

x and y

number 1 : x

number 2 : y

A.T.Q.:

x + y = - 34

x - y = 5

x + y = - 34, x - y = 5 : x = - \frac{29}{2}, y = - \frac{39}{2}

仮分数を帯分数に変換する:

\frac{29}{2} = 14 \frac{1}{2}

仮分数を帯分数に変換する:

\frac{39}{2} = 19 \frac{1}{2}

The numbers : - 14 \frac{1}{2}, - 19 \frac{1}{2}
