Wrath of Math | Linear Systems Using Row Operations and Back Substitution | Linear Algebra Exercises @WrathofMath | Uploaded 2 months ago | Updated 9 hours ago
We show how to solve linear systems of equations using row operations on an augmented matrix and back substitution. This process is known as Gaussian elimination. We'll solve an example of a linear system with a unique solution and a linear system with infinitely many solutions. #linearalgebra
