Gaussian elimination method is used to solve linear equation by reducing the rows. Gaussian elimination is also known as Gauss jordan method and reduced row echelon form. Gauss jordan method is used to solve the equations of three unknowns of the form a1x+b1y+c1z=d1, a2x+b2y+c2z=d2, a3x+b3y+c3z=d3. This reduced row echelon form online calculator let you to solve the system of a linear equation by entering the values.
Reduced row echelon form is explained as the gauss jordan method which is operated on rows, and column echelon form means that the gauss jordan is operated on columns.
