17) Write a system of equations with the solution. Many answers. Ex: x + y + z = 3, 2 x + y + z = 5, x + 2 y − z = 4. Create your own worksheets like this one with Infinite Algebra 2. Free trial available at KutaSoftware.com.
8 Απρ 2019 · Video tutorial with example questions and problems on Gaussian Elimination and Gauss-Jordan Elimination to solve a system of Linear Equations.
This procedure is called Gauss-Jordan elimination. Write the augmented matrix of the system of linear equations. Use elementaray row operations to reduce the augmented matrix into (reduced) row echelon form.
The Gauss-Jordan Elimination process brings a ma-trix into reduced row echelon form. It consists of ele-mentary row operations: Swap two rows. Scale a row. Subtract a multiple of a row from an other.
