x+2\geq 0 x+7<0
For the quotient to be ≤0, one of the values x+2 and x+7 has to be ≥0, the other has to be ≤0, and x+7 cannot be zero. Consider the case when x+2\geq 0 and x+7 is negative.
x\in \emptyset
This is false for any x.
x+2\leq 0 x+7>0
Consider the case when x+2\leq 0 and x+7 is positive.
x\in (-7,-2]
The solution satisfying both inequalities is x\in \left(-7,-2\right].
x\in (-7,-2]
The final solution is the union of the obtained solutions.
