WebSep 17, 2024 · Consider the reduced row echelon form of the augmented matrix of a system of linear equations.\(^{1}\) If there is a leading 1 in the last column, the system has no solution. Otherwise, if there is a leading 1 for each variable, then there is exactly one solution; otherwise (i.e., there are free variables) there are infinite solutions. WebSep 17, 2024 · Key Idea 2.5. 1: Solving A X = B. Let A be an n × n matrix, where the reduced row echelon form of A is I. To solve the matrix equation A X = B for X, Form the augmented matrix [ A B]. Put this matrix into reduced row echelon form. It will be of the form [ I X], where X appears in the columns where B once was.
