Question
![**Problem Statement:**
Solve the first-order linear equation
\[ e^x y' + 3e^x y = 2x e^{-5x}, \quad y(1) = 232. \]
**Description:**
This is a first-order linear ordinary differential equation where \( y' \) denotes the derivative of \( y \) with respect to \( x \). The equation is presented in the form:
\[ P(x)y' + Q(x)y = g(x), \]
where \( P(x) = e^x \), \( Q(x) = 3e^x \), and \( g(x) = 2x e^{-5x} \).
**Initial Condition:**
The required solution must satisfy the initial condition \( y(1) = 232 \).
To solve this differential equation, we aim to find the integrating factor or use an appropriate method for first-order linear equations and apply the initial condition to find a specific solution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb365fa56-db01-4f82-bc2c-5bb5151e447e%2Fb525fe80-0aef-4dfd-a2e8-d40e283e5f20%2Ff05vvga_processed.png&w=3840&q=75)
