解不等式 $|3x+2|<3|2x-1|$。

Answer all questions. You should use a calculator where appropriate.

You must show all necessary working clearly; no marks will be given for unsupported answers from a calculator.

Give non-exact numerical answers correct to 3 significant figures, or 1 decimal place for angles in degrees, unless a different level of accuracy is specified in the question.

请回答所有题目。适当时应使用计算器。必须清楚展示所有必要的计算过程；仅给出计算器答案而没有过程，不予评分。除非题目另有精度要求，非精确数值答案保留 3 位有效数字，以度为单位的角度保留 1 位小数。

两边都非负，可以等价平方。因式分解后用符号判断，严格不等式不包括临界点。

Both sides are nonnegative, so squaring preserves the inequality:

Rearranging,

The product is positive outside its two roots. Hence
