Step 2: Look at the first column. If the value in the first row is not zero, use it as pivot. If not, check the column for a non zero element, and permute rows if necessary so that the pivot is in the first row of the column. Websolve. Since every system can be represented by its augmented matrix, we can carry out the transformation by performing operations on the matrix. De nition 1. A matrix is in row echelon form if 1.
