($-\infty, -2)$

Work Step by Step

$Solve$ $the$ $linear$ $inequality$. $Express$ $the$ $solution$ $using$ $interval$ $notation$ $and$ $graph$ $the$ $solution$ $set$: $3x + 11 \lt 5$ Solve for x $3x +11 \lt 5$ Subtract both sides by 11 $3x +11-11 \lt 5-11$ $3x \lt -6$ Divide both sides by 3 $\frac{3x}{3} \lt -\frac{6}{3}$ $x \lt -2$ Express the solution in interval notation form ($-\infty, -2)$ Graph the solution set
