3x+3\geq 0 x+2<0
For the quotient to be ≤0, one of the values 3x+3 and x+2 has to be ≥0, the other has to be ≤0, and x+2 cannot be zero. Consider the case when 3x+3\geq 0 and x+2 is negative.
x\in \emptyset
This is false for any x.
3x+3\leq 0 x+2>0
Consider the case when 3x+3\leq 0 and x+2 is positive.
x\in (-2,-1]
The solution satisfying both inequalities is x\in \left(-2,-1\right].
x\in (-2,-1]
The final solution is the union of the obtained solutions.
