1. **State the problem:** Solve the equation $$\frac{2x+3}{4} = 5$$ for $x$.
2. **Formula and rules:** To solve for $x$, we need to isolate $x$ on one side of the equation. We can do this by eliminating the denominator and then solving the resulting linear equation.
3. **Eliminate the denominator:** Multiply both sides of the equation by 4 to cancel the denominator:
$$4 \times \frac{2x+3}{4} = 4 \times 5$$
This simplifies to:
$$\cancel{4} \times \frac{2x+3}{\cancel{4}} = 20$$
So,
$$2x + 3 = 20$$
4. **Isolate $x$:** Subtract 3 from both sides:
$$2x + 3 - 3 = 20 - 3$$
$$2x = 17$$
5. **Solve for $x$:** Divide both sides by 2:
$$\frac{2x}{2} = \frac{17}{2}$$
$$\cancel{2}x / \cancel{2} = \frac{17}{2}$$
$$x = \frac{17}{2}$$
6. **Final answer:** The solution to the equation is
$$x = \frac{17}{2}$$ or 8.5.
This means when $x$ is 8.5, the original equation holds true.
