![### General Solution for the Differential Equation
**Problem Statement:**
Find the general solution of the given differential equation.
\[
3 \frac{dy}{dx} + 21y = 7
\]
**Solution:**
The general solution is:
\[
y(x) = \text{(Your Solution Here)}
\]
**Determining the Largest Interval \( I \):**
Give the largest interval \(I\) over which the general solution is defined. (Think about the implications of any singular points. Enter your answer using interval notation.)
\[
(-\infty, \infty)
\]
**Transient Terms Identification:**
Determine whether there are any transient terms in the general solution.
\[
\text{(Your Answer Here)}
\]
**Explanation of Concepts:**
1. **Solving Linear Differential Equations**:
- This equation is a first-order linear ordinary differential equation (ODE).
- The standard form is \( \frac{dy}{dx} + P(x)y = Q(x) \).
2. **Finding Integrating Factor**:
- The integrating factor \( \mu(x) \) is calculated as \( e^{\int P(x) dx} \).
3. **Solving the Integral**:
- Once the integrating factor is determined, both sides of the ODE are multiplied by it to simplify the solving process.
**Note**: The blanks indicate places where specific solutions or terms should be calculated and filled in, based on solving the ODE.
