解答

展开

\frac{144 ( 57 - 37 y )}{10615}

\frac{8208}{10615} - \frac{5328 y}{10615}

求解步骤

\frac{144 ( 57 - 37 y )}{10615}

乘开

144 (57 - 37 y) : 8208 - 5328 y

= \frac{8208 - 5328 y}{10615}

使用分式法则:

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

\frac{8208 - 5328 y}{10615} = \frac{8208}{10615} - \frac{5328 y}{10615}

= \frac{8208}{10615} - \frac{5328 y}{10615}
