展开

\frac{11 ( x - 24 )}{2}

\frac{11 x}{2} - 132

求解步骤

\frac{11 ( x - 24 )}{2}

乘开

11 (x - 24) : 11 x - 264

= \frac{11 x - 264}{2}

使用分式法则:

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

\frac{11 x - 264}{2} = \frac{11 x}{2} - \frac{264}{2}

= \frac{11 x}{2} - \frac{264}{2}

数字相除:

\frac{264}{2} = 132

= \frac{11 x}{2} - 132
