1. **State the problem:** Solve the equation $$\frac{2x+3}{x-1} = 4$$ for $x$.
2. **Formula and rules:** To solve a rational equation, multiply both sides by the denominator to eliminate the fraction, but remember to check for values that make the denominator zero (excluded values).
3. **Multiply both sides by the denominator:**
$$\cancel{(x-1)} \cdot \frac{2x+3}{\cancel{x-1}} = 4 \cdot (x-1)$$
which simplifies to
$$2x + 3 = 4(x - 1)$$
4. **Expand the right side:**
$$2x + 3 = 4x - 4$$
5. **Bring all terms to one side:**
$$2x + 3 - 4x + 4 = 0$$
which simplifies to
$$-2x + 7 = 0$$
6. **Solve for $x$:**
$$-2x = -7$$
$$x = \frac{-7}{-2} = \frac{7}{2}$$
7. **Check for excluded values:**
The denominator $x-1$ cannot be zero, so $x \neq 1$. Since $x=\frac{7}{2}$ is not excluded, it is a valid solution.
**Final answer:**
$$x = \frac{7}{2}$$
