Solving Linear Equations

Our aim is to find the values of the n unknowns x1, x2, x3, …, xn that simultaneously satisfy the system of m linear equations

Gaussian elimination

To find the solution of these equations we use a method called Gaussian elimination. There are five steps to Gaussian elimination.

  1. Create the augmented matrix.
  2. Row reduces the matrix into reduced form.
  3. Reform the equations from the reduced form.
  4. Solve by back substitution.
  5. Check answer.
