To solve the inequality
\[ \frac{s}{-1} + 4 \geq -3, \]
we can first isolate the term involving \( s \). Let's start by subtracting 4 from both sides:
\[ \frac{s}{-1} \geq -3 - 4, \]
which simplifies to
\[ \frac{s}{-1} \geq -7. \]
Next, to eliminate the fraction, we can multiply both sides by -1. Remember that when we multiply or divide an inequality by a negative number, we need to reverse the inequality sign:
\[ s \leq 7. \]
Thus, the solution to the inequality is
\[ s \leq 7. \]
