Systems of Three Variables 2, Systems of Equations and Inequalities, Algebra II

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

In this systems of equations learning exercise, students solve 13 systems of equations.  Students use elimination to solve three variable systems of equations.

Sal solves a challenging problem that consists of a system of three trigonometric equations and three unknowns.

How does solving a system of three equations compare to solving two-variable equations? The video tutorial shows how to utilize the same methods of substitution and elimination to solve a system of three equations. The instructor solves...

Which method of solving systems is the best? Individuals watch the same system solved using elimination, then substitution, and finally graphing. They can compare the different methods and see how each method results in the same solution.

This video demonstrates how to solve a system comprised of three equations in three variables using elimination. [7:00]

How many different ways can three planes intersect? The interactive provides three movable planes. Pupils manipulate the planes to determine the number of solutions possible based upon their intersections.

This lesson video shows how to solve a system of three equations with three unknown.

Given a system of three linear equations, the student will solve the system with a unique solution.

This video demonstrates how to solve a system comprised of three equations in three variables. [8:23]
