解答

展开

\frac{11 ( 64 - 15 z )}{2}

352 - \frac{165 z}{2}

求解步骤

\frac{11 ( 64 - 15 z )}{2}

乘开

11 (64 - 15 z) : 704 - 165 z

= \frac{704 - 165 z}{2}

使用分式法则:

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

\frac{704 - 165 z}{2} = \frac{704}{2} - \frac{165 z}{2}

= \frac{704}{2} - \frac{165 z}{2}

数字相除:

\frac{704}{2} = 352

= 352 - \frac{165 z}{2}
