1. **State the problem:** Solve the equation $$\sqrt{5x - 1} + 4 = 11$$ for $x$.
2. **Isolate the square root term:** Subtract 4 from both sides to get $$\sqrt{5x - 1} = 11 - 4$$
3. Simplify the right side: $$\sqrt{5x - 1} = 7$$
4. **Square both sides** to eliminate the square root:
$$\left(\sqrt{5x - 1}\right)^2 = 7^2$$
$$5x - 1 = 49$$
5. **Solve for $x$:** Add 1 to both sides:
$$5x = 49 + 1$$
$$5x = 50$$
6. Divide both sides by 5:
$$x = \frac{50}{5}$$
$$x = 10$$
7. **Check the solution:** Substitute $x=10$ back into the original equation:
$$\sqrt{5(10) - 1} + 4 = \sqrt{50 - 1} + 4 = \sqrt{49} + 4 = 7 + 4 = 11$$
The left side equals the right side, so $x=10$ is the correct solution.
