Can a matrix have more than one echelon form

WebSep 17, 2024 · Notice how the above RREF form of matrix A is different from what we have seen in the past. In this case not all of our values for \(x\) are unique. When we write down a solution to this problem by defining the variables by one or more of the undefined variables. for example, here we can see that \(x_4\) is undefined. WebA.
