Answer
No solution.
Work Step by Step
The given inequality is
$\Rightarrow 6(l+3)\lt 3(2l+6)$
Use distributive property.
$\Rightarrow 6l+18\lt 6l+18$
Add $-6l-18$ to each side.
$\Rightarrow 6l+18-6l-18\lt 6l+18-6l-18$
Simplify.
$\Rightarrow 0\lt 0$
The inequality is false.
Hence, there is no solution.
