### Problem Statement:
3. Let \( A \) be an \( m \times n \) matrix and \( b \in \mathbb{R}^m \). Given that \( A\textbf{x} = b \) has two distinct solutions \( u \) and \( v \), explain why \( A\textbf{x} = b \) has infinitely many solutions.
---
In this problem, we are given a linear system represented by a matrix equation \( A\textbf{x} = b \). Here, \( A \) is an \( m \times n \) matrix, and \( b \) is a vector in \( \mathbb{R}^m \). The problem statement reveals that there are at least two distinct solutions to this equation, \( u \) and \( v \). The objective is to explain why the existence of these two distinct solutions implies that there are infinitely many solutions to the equation \( A\textbf{x} = b \).
