Start with the compound inequality given: \(1 < \frac{x - 2}{2} \le 4\).
To eliminate the fraction, multiply all parts of the inequality by 2 (which is positive, so the inequality signs remain the same): \(1 \times 2 < (x - 2) \le 4 \times 2\), which simplifies to \(2 < x - 2 \le 8\).
Next, isolate \(x\) by adding 2 to all parts of the inequality: \(2 + 2 < x - 2 + 2 \le 8 + 2\), resulting in \(4 < x \le 10\).
Interpret the inequality \(4 < x \le 10\) in interval notation. Since \(x\) is strictly greater than 4 but less than or equal to 10, the interval is \((4, 10]\).
This interval represents all values of \(x\) that satisfy the original compound inequality.
