A precise definition of reduced row echelon form follows.
Gonick, L. It is also in reduced form because all the pivots are
equal to
and the non-pivotal elements in the basic columns are all equal to
. , vectors having one entry equal to 1 and all the other entries
equal to 0). The following image (from the Old Dominion University Calculator shows how the matrix [01, 00, 59] is reduced to row echelon form with two simple row operations:

Please use ide. Note that x and y are in the same positions as when you converted the equation in step 1, so all you have to do is read the solution:

\begin{align*}
x_1= 2, \\
-2x_1 + x_2 = 3, \\
5x_1-4x_2 +x_3 = 2
\end{align*}(a) Find the coefficient matrix and its inverse matrix. Reduced row echelon form has four requirements:Any matrix can be transformed to reduced row echelon form, using a technique called Gaussian elimination. In fact, of you use the ODU online calculator, it will even provide the row operations for you.

In particular, remember that a matrix is in row echelon form if and only if:
all its non-zero rows have an entry, called pivot, that is click now and has
only zero entries below it and to its left;
zero-rows (if there are any) are below the non-zero rows.
