解答

展开

\frac{144 ( 13 x + 10 )}{13}

144 x + \frac{1440}{13}

求解步骤

\frac{144 ( 13 x + 10 )}{13}

乘开

144 (13 x + 10) : 1872 x + 1440

= \frac{1872 x + 1440}{13}

使用分式法则:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{1872 x + 1440}{13} = \frac{1872 x}{13} + \frac{1440}{13}

= \frac{1872 x}{13} + \frac{1440}{13}

数字相除:

\frac{1872}{13} = 144

= 144 x + \frac{1440}{13}
