(-3)/((k-8))=(5k)/(16)

解

\frac{- 3}{( k - 8 )} = \frac{5 k}{16}

k = \frac{4 ( 5 + 10 )}{5}, k = \frac{4 ( 5 - 10 )}{5}

十進法表記

k = 6.52982 \dots, k = 1.47017 \dots

解答ステップ

\frac{- 3}{( k - 8 )} = \frac{5 k}{16}

たすき掛け

- 48 = (k - 8) \cdot 5 k

解く

- 48 = (k - 8) \cdot 5 k : k = \frac{4 ( 5 + 10 )}{5}, k = \frac{4 ( 5 - 10 )}{5}

k = \frac{4 ( 5 + 10 )}{5}, k = \frac{4 ( 5 - 10 )}{5}
