Question

Solve the following inequality: $2x-1<5$

Answer 1

$2x-1<5$

$2x<5+1$

$2x<6$

$x<3$

The above inequality is represented by the number line in the figure.

All real numbers less than $3$ are included.

There is a hollow circle on $3$, because $3$ is not included in the solution of the inequality.
