d(x)=(-6)/(-3x+4)

解

d (x) = \frac{- 6}{- 3 x + 4}

x = - \frac{- 4 d + 16 d ^{2} + 72 d}{6 d}, x = - \frac{- 4 d - 16 d ^{2} + 72 d}{6 d}; d \neq = 0

解答ステップ

d (x) = \frac{- 6}{- 3 x + 4}

簡素化

\frac{- 6}{- 3 x + 4} : - \frac{6}{- 3 x + 4}

d (x) = - \frac{6}{- 3 x + 4}

以下で両辺を乗じる:

- 3 x + 4

d x (- 3 x + 4) = - 6

解く

d x (- 3 x + 4) = - 6 : x = - \frac{- 4 d + 16 d ^{2} + 72 d}{6 d}, x = - \frac{- 4 d - 16 d ^{2} + 72 d}{6 d}; d \neq = 0

x = - \frac{- 4 d + 16 d ^{2} + 72 d}{6 d}, x = - \frac{- 4 d - 16 d ^{2} + 72 d}{6 d}; d \neq = 0
