#### Answer

Subtract $\frac{1}{3}$ from each side.

#### Work Step by Step

To solve an inequality, you need to isolate the variable on one side of the inequality.
$l+\frac{1}{3}\geq\frac{7}{3}\longrightarrow$ subtract $\frac{1}{3}$ from each side to isolate l on the left side
$l+\frac{1}{3}-\frac{1}{3}\geq\frac{7}{3}-\frac{1}{3}\longrightarrow$ subtract
$l\geq\frac{6}{3}$
