WebJan 27, 2024 · To solve this system, the matrix has to be reduced into reduced echelon form. Step 1: Switch row 1 and row 3. All leading zeros are now below non-zero leading entries. Step 2: Set row 2 to row 2 plus (-1) times row 1. In other words, subtract row 1 from row 2. This will eliminate the first entry of row 2. Step 3: Multiply row 2 by 3 and row 3 by 2. A matrix is in row echelon form(ref) when it satisfies the following conditions. 1. The first non-zero element in each row, called the leading entry, is 1. 2. Each leading entry is in a column to the right of the leading entry in the previous row. 3. Rows with all zero elements, if any, are below rows having a non-zero … See more A matrix is in reduced row echelon form(rref) when it satisfies the following conditions. 1.
