Question
![### Linear Programming Problem
**Objective:**
Maximize:
\[ x + y \]
**Subject to Constraints:**
\[ x + 2y \leq 4 \]
\[ 2x + y \leq 4 \]
\[ 0 \leq 3x \leq 5 \]
\[ 0 \leq y \]
### Tasks:
(a) Convert the problem to a standard form Linear Programming (LP) problem.
(b) Find a canonical form of the system in part (a).
(c) Find the basic solution for basic variables \( x_1, x_4, \) and \( x_5 \). Is this solution feasible?
### Notes:
- **Standard Form**: Linear programming problems in standard form have all constraints as equalities, and all variables are non-negative.
- **Canonical Form**: A form that is derived from the standard form where basic and non-basic variables are separated.
- **Basic Solution**: This involves setting non-basic variables to zero and solving for the basic variables. Feasibility refers to whether the solution satisfies all constraints.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8fde1064-a6b6-4339-9493-cdb828b8cc21%2F28a089b5-5441-4ae4-9dea-b9bcb0974632%2Frtb3eyn_processed.jpeg&w=3840&q=75)
