All absolute value expressions are greater than or equal to zero. It follows then that any absolute value expression is greater than all negative numbers.
|2s-7|≥ 0 ⇒ |2s-7|>-1
This means any value of s will satisfy the inequality. Therefore, there are infinitely many solutions, and the solution set is the set of all real numbers.
We can represent this graphically on a number line by showing that all values are included in the solution set, so all values are shaded.
