Answer
$x\lt 2$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow 4x\lt 8$
Divide each side by $4$.
$\Rightarrow \frac{4x}{4}\lt \frac{8}{4}$
Simplify.
$\Rightarrow x\lt 2$
Hence, the solution is $x\lt 2$.
Use an open circle because $2$ is not a solution.
Shade the number line on the left side.
