\frac{26}{7} \leq n \leq \frac{96}{7}

+2

间隔符号

[\frac{26}{7}, \frac{96}{7}]

十进制

3.71428 \dots \leq n \leq 13.71428 \dots

求解步骤

29 \leq 7 n + 3 \leq 99

若

a \leq u \leq b

，则

a \leq u and u \leq b

29 \leq 7 n + 3 and 7 n + 3 \leq 99

29 \leq 7 n + 3 : n \geq \frac{26}{7}

7 n + 3 \leq 99 : n \leq \frac{96}{7}

合并区间

n \geq \frac{26}{7} and n \leq \frac{96}{7}

合并重叠的区间

\frac{26}{7} \leq n \leq \frac{96}{7}

流行的例子

2x+5<3x+8<-x+16

2 x + 5 < 3 x + 8 < - x + 16

(-2)/3 <-x/3+2<= 2/3

\frac{- 2}{3} < - \frac{x}{3} + 2 \leq \frac{2}{3}

-2<= ((5-3x))/4 < 1/2

- 2 \leq \frac{( 5 - 3 x )}{4} < \frac{1}{2}

- 7 < 2 x - 3 < 9

x-2<2 x/3-2<3 x/2-1/3

x - 2 < 2 \frac{x}{3} - 2 < 3 \frac{x}{2} - \frac{1}{3}
