If only a closed point at (3) is shown on the number line, what is the solution?

Answer and explanation

Correct answer: \(x=3\)

A single closed point at 3 means that 3 is included in the solution set and no other value is included. Hence, the solution is \(x=3\). For \(x>3\) or \(x<3\), a ray would extend to the right or left of the point respectively. Exam tip: one isolated closed point represents exactly one value.
