WebThe row reductions had a single element left over in the last row. This gets scaled regardless of the value of d (unless d = 9 in which case it should be zero) This means that the row reduced form is as you have shown. The operations to reach that form do however still depend on the value of d. Step one was, row 3 gets one of row 1 subtracted.
