Sophia: Using Elementary Row Operations to Solve for Systems of Equations

Apply different algebraic concepts to solve a system of equations using substitution. The video tutorial explains each step of the process. The instructor then shows how to check the solution to ensure it is the proper answer.

What happens when equations are multiples of each other? Pupils see the process of solving a system of equations by graphing. The informative video example shows two equations written in different forms that are actually the same line....

This lesson presents how to use elementary row operations to solve for a system of linear equations. It is 1 of 4 in the series titled "Using Elementary Row Operations to Solve for Systems of Equations."

This video lesson demonstrates how to solve a system of linear equations by using matrix row operations. Students can check their understanding with an assessment.

Two equations. Wait! They don't look like the same kind of equations. How do you solve a system of equations when one equation is linear and the other is a quadratic? Watch this video as the instructor illustrates how to use the...
