簡約 (-1/8 c+16)-(3/8+3c)

解

簡約

(- \frac{1}{8} c + 16) - (\frac{3}{8} + 3 c)

\frac{- c - 3}{8} + 16 - 3 c

解答ステップ

(- \frac{1}{8} c + 16) - (\frac{3}{8} + 3 c)

規則を適用する:

(a) = a

(- \frac{1}{8} c + 16) = - \frac{1}{8} c + 16

= - \frac{1}{8} c + 16 - (\frac{3}{8} + 3 c)

- \frac{1}{8} c = - \frac{c}{8}

- (\frac{3}{8} + 3 c) = - \frac{3}{8} - 3 c

= - \frac{c}{8} + 16 - \frac{3}{8} - 3 c

結合

- \frac{c}{8} + 16 - \frac{3}{8} - 3 c : \frac{- c - 3}{8} + 16 - 3 c

= \frac{- c - 3}{8} + 16 - 3 c
