Elementary Row Operations - Mathematics Home

Elementary Row OperationsOur goal is to begin with an arbitrary matrix and apply Operations thatrespect row equivalence until we have a matrix in Reduced Row EchelonForm (RREF). The three Elementary row Operations are: (Row Swap) Exchange any two rows. (Scalar Multiplication) Multiply any row by a constant. (Row Sum) Add a multiple of one row to another do these preserve the linear system in question? Swapping rows isjust changing the order of the equations begin considered, which certainlyshould not alter the solutions. Scalar multiplication is just multiplying theequation by the same number on both sides, which does not change thesolution(s) of the equation. Likewise, if two equations share a commonsolution, adding one to the other preserves the is a very simple process for row reducing a matrix, working columnby column.

Wikipedia, Systems of Linear Equations Review Problems 1.Explain why row equivalence is not a ected by removing columns. Is row equivalence a ected by removing rows? Prove or give a counter-example. 2.(Gaussian Elimination) Another method for solving linear systems is to use row operations to bring the augmented matrix to row-echelon form.
