WebSep 16, 2024 · It turns out that it is possible for the augmented matrix of a system with no solution to have any rank r as long as r > 1. Therefore, we must know that the system is consistent in order to use this theorem! Unique Solution Suppose r = n. Then, there is a pivot position in every column of the coefficient matrix of A. WebIf a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.
