解答

展开

4 (\frac{13 - 2 ( \frac{50}{24 - x} )}{6} + 3 = 5)

\frac{- 26 x + 424}{- 3 x + 72} + 12 = 5

求解步骤

4 (\frac{13 - 2 ( \frac{50}{24 - x} )}{6} + 3 = 5)

= 4 (\frac{13 - 2 ( \frac{50}{24 - x} )}{6} + 3 \cdot 5 =)

使用分配律:

a (b + c) = ab + a c

a = 4, b = \frac{13 - 2 ( \frac{50}{24 - x} )}{6}, c = 3 = 5

4 \cdot \frac{13 - 2 ( \frac{50}{24 - x} )}{6} + 4 \cdot 3 = 5

乘开

4 \cdot \frac{13 - 2 ( \frac{50}{24 - x} )}{6} + 4 \cdot 3 : \frac{- 26 x + 424}{- 3 x + 72} + 12

\frac{- 26 x + 424}{- 3 x + 72} + 12 = 5

e x p an d 2 (m + 1 = 5)

e x p an d \frac{k ( s + 1 )}{( s + 2 ) ( s + 3 )}

e x p an d \frac{2 x + b}{( x ^{2} + b x + c ) ^{2}}

e x p an d \frac{x ^{3}}{( x + 3 ) ^{2}}

e x p an d - e^{- 0.01 x - 0.01 h (x)} - 0.18 x - 0.18 h (x) + 7 - (f (x) = - e^{- 0.01 x} - 0.18 x + 7)
