十进制

- 1.20833 \dots \leq x \leq 0.91666 \dots

求解步骤

- 2 \leq \frac{1}{2} - 3 x + \frac{1}{4} \leq \frac{35}{8}

若

a \leq u \leq b

，则

a \leq u and u \leq b

- 2 \leq \frac{1}{2} - 3 x + \frac{1}{4} and \frac{1}{2} - 3 x + \frac{1}{4} \leq \frac{35}{8}

- 2 \leq \frac{1}{2} - 3 x + \frac{1}{4} : x \leq \frac{11}{12}

\frac{1}{2} - 3 x + \frac{1}{4} \leq \frac{35}{8} : x \geq - \frac{29}{24}

合并区间

x \leq \frac{11}{12} and x \geq - \frac{29}{24}

合并重叠的区间

- \frac{29}{24} \leq x \leq \frac{11}{12}
