Inequality X Greater 1 C7D725
1. We are asked to solve the inequality $$2 < \frac{2x + 3}{x + 1} < \frac{5}{2}$$ for real numbers $x$ such that $x > 1$.
2. Important: Since $x > 1$, the denominator $x + 1 > 0$, so we can multiply inequalities by $x + 1$ without reversing inequality signs.
3. Solve the left inequality:
$$2 < \frac{2x + 3}{x + 1}$$
Multiply both sides by $x + 1$:
$$2(x + 1) < 2x + 3$$
Simplify:
$$2x + 2 < 2x + 3$$
Subtract $2x$ from both sides:
$$2 < 3$$
This is always true.
4. Solve the right inequality:
$$\frac{2x + 3}{x + 1} < \frac{5}{2}$$
Multiply both sides by $x + 1$:
$$2x + 3 < \frac{5}{2}(x + 1)$$
Multiply out the right side:
$$2x + 3 < \frac{5}{2}x + \frac{5}{2}$$
Multiply both sides by 2 to clear fractions:
$$4x + 6 < 5x + 5$$
Subtract $4x$ from both sides:
$$6 < x + 5$$
Subtract 5 from both sides:
$$1 < x$$
5. Since $x > 1$ is given, the right inequality holds for all $x > 1$.
6. Conclusion: For all real $x$ such that $x > 1$, the inequality $$2 < \frac{2x + 3}{x + 1} < \frac{5}{2}$$ holds true.
Final answer:
$$\boxed{\text{For all } x > 1, \quad 2 < \frac{2x + 3}{x + 1} < \frac{5}{2}}$$
