不等式計算器

解不等式

此計算器將嘗試求解線性、二次、多項式、有理式以及絕對值不等式。它也能處理複合不等式與不等式組。

若要繪製不等式的圖形，請使用圖形計算器。

Enter inequalities:
Enter compound inequalities as 4<2x+5<=7, separate inequalities by commas.
For absolute values, use abs: 2<=abs(3x-4)<5 will be treated as `2<=|3x-4|<5`.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Your input: solve $$$2 \lt \left|{x - 1}\right| \leq 4$$$
