The solution format of inequality with absolute value in higher one X-3 ≤ x I think the reference answers are written in x0 discussion The solution set is {x x ≥ 3 / 2} I have some ideas, but I don't know how to write them Because the examples in the book are not very deep. So I don't know how to write the format Another question: It is known that a = {X-1 ≥ a}, B = {X-6}

X-3 ≤ x is - x ≤ x-3 ≤ x, and then it is divided into two solutions
|X | > A is x > A or X
