Question: Solve for $x$ at $g(x) = 4$ given the function below.
g(x) = 1 + \frac{x}{5}
x =
1. **State the problem:** We need to find the value of $x$ such that $g(x) = 4$ for the function $$g(x) = 1 + \frac{x}{5}$$.
2. **Write the equation to solve:** Set the function equal to 4:
$$1 + \frac{x}{5} = 4$$
3. **Isolate the term with $x$:** Subtract 1 from both sides:
$$\frac{x}{5} = 4 - 1$$
$$\frac{x}{5} = 3$$
4. **Solve for $x$:** Multiply both sides by 5 to cancel the denominator:
$$\cancel{5} \times \frac{x}{\cancel{5}} = 3 \times 5$$
$$x = 15$$
5. **Answer:** The value of $x$ that makes $g(x) = 4$ is $$\boxed{15}$$.
