Answer
All real numbers are solutions.
Work Step by Step
The given inequality is
$\Rightarrow 9j-6+6j\geq 3(5j-2)$
Use distributive property.
$\Rightarrow 15j-6\geq 15j-6$
Add $-15j+6$ to each side.
$\Rightarrow 15j-6-15j+6\geq 15j-6-15j+6$
Simplify.
$\Rightarrow 0\geq 0$
The inequality is true.
Hence, all real numbers are solutions.
