Web2. Each leading entry of a row is in a column to the right of the leading entry of the row above it. 3. All entries in a column below a leading entry are zeros. For it to be in reduced … WebIn fact, the system is inconsistent if and only if one of the equations of the canonical form is reduced to 0 = 1. [7] Otherwise, regrouping in the right hand side all the terms of the equations but the leading ones, expresses the variables corresponding to the pivots as constants or linear functions of the other variables, if any. WebYour calculator took the extra step of dividing the final row by -4, which doesn't change the zero entries and which makes the final entry 1. Sal probably didn't put the final row in reduced form because he could see the contradiction coming. (0 = -4 is as much a contradiction as 0 = 1). hillock international school
