1. The problem is to solve the inequality $$\frac{12q}{x} > 43$$ for $x$.
2. We want to isolate $x$ on one side. Since $x$ is in the denominator, we multiply both sides by $x$, but we must consider the sign of $x$ because multiplying or dividing by a negative number reverses the inequality.
3. Case 1: $x > 0$
Multiply both sides by $x$ (positive, so inequality direction stays the same):
$$12q > 43x$$
4. Divide both sides by 43:
$$\frac{12q}{\cancel{43}} > x \cancel{\frac{1}{43}}$$
So,
$$x < \frac{12q}{43}$$
5. Case 2: $x < 0$
Multiply both sides by $x$ (negative, so inequality direction reverses):
$$12q < 43x$$
6. Divide both sides by 43:
$$\frac{12q}{\cancel{43}} < x \cancel{\frac{1}{43}}$$
So,
$$x > \frac{12q}{43}$$
7. Since the problem states $x > 43$, we combine this with the above results:
- For $x > 0$, $x < \frac{12q}{43}$ and $x > 43$ must both hold.
- For $x < 0$, $x > \frac{12q}{43}$ and $x < 0$ must both hold.
8. The solution depends on the value of $q$ and the relation between $\frac{12q}{43}$ and 43.
Summary:
- If $x > 0$, then $43 < x < \frac{12q}{43}$.
- If $x < 0$, then $\frac{12q}{43} < x < 0$.
This is the solution for $x$ given the inequality and the condition $x > 43$.
