There are two points on the number axis where the distance to the origin is equal to 2, which are +2 and -2. Use the absolute value to understand that the distance to the origin on the number axis is equal to 2 There are two points on the number axis where the distance to the origin is equal to 2, which are +2 and -2. Use the absolute value to understand to the origin on the number axis is equal to 2

X=2, x=-2
It is known that the absolute value 5 is equal to the absolute value of 5 minus 0, and its meaning on the number axis is the distance between the point representing 5 and the origin (i.e. the point representing 0). Again, the absolute value of expression 6-3, whose meaning on the number axis is the distance between points representing 6, similarly, what is the meaning of the absolute value of expression a plus 5 on the number axis It is known that the absolute value 5 is equal to the absolute value of 5 minus 0, and its meaning on the number axis is the distance between the point representing 5 and the origin (i.e. the point representing 0). Again, the absolute value of equation 6-3, whose meaning on the number axis is the distance between points representing 6, similarly, what is the meaning of the absolute value of equation a plus 5 on the number axis
A +5 can be written as a -(-5), that is, the distance between a and -5.

- 1. The set of solutions of absolute value inequality x whose absolute value is less than or equal to (a is greater than or equal to 0) can be obtained as follows: the geometric meaning of the absolute value of x whose absolute value is less than or equal to a on the number axis is "the distance to the origin is not more than a ", so its solution set is -a greater than or equal to x less than or equal to a. According to the above, the following inequality can be solved:(1) the absolute value of x is less than or equal to 3(2) the absolute value of 2x-1 is less than or equal to 5 The set of solutions of absolute value inequality x whose absolute value is less than or equal to (a is greater than or equal to 0) can be obtained as follows: the geometric meaning of the absolute value of x whose absolute value is less than or equal to a on the number axis is that the distance to the origin is not more than a, so its solution set is that -a is greater than or equal to x whose absolute value is less than or equal to a.
