Solve a system of equations using Elementary Row Operations

WebDoing elementary row operations corresponds to multiplying on the left by an elementary matrix. For example, the row operation of "new R2 = R2 - 3R1" is produced on a 3 by n matrix when you multiply on the left by ( 1 0 0 − 3 1 0 0 0 1). Column operations, on the other hand, are produced when you multiply by a matrix on the right hand side. WebNow, I will transform the RHS matrix to an upper diagonal matrix. I can exchange the first and the last rows. Exchanging any two rows changes the sign of the determinant, and therefore. det [ 2 3 10 1 2 − 2 1 1 − 3] = − det [ 1 1 − 3 0 1 1 0 0 15] The matrix on the RHS is now an upper triangular matrix and its determinant is the product ... flair flight 517

"WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A). " - How to solve row operations
