Khan Academy: Non Linear Systems of Equations: Systems of Nonlinear Equations 3

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.

A video demonstration on how to find the solution of two systems of equations.

The second in a series of video lessons on solving non-linear systems of equations.

A video lesson on solving a non-linear system of equations graphically.

This video begins by finishing the final problem in the "Age Word Problems 2" video. Then it continues to demonstrate how to solve word problems related to a person's age by setting up and solving equations based on the information given...

This video demonstrates how to solve word problems related to a person's age by setting up and solving equations based on the information given in the problem. There are two sample word problems. [7:14]

A video that demonstrates how to solve a multi-step linear equation. There are two sample problems that contain only integers. Practice problems available. [6:44]

This video demonstrates how to solve linear equations in which the variable "x" is in the denominator. There are three different sample problems presented. Practice problems available. [7:39]

A video that demonstrates how to solve linear equations of the form Ax=B. There are three examples that vary using whole numbers and positive and negative fractions. [7:28]

A video that demonstrates how to solve equations of the form Ax + B = C. There are two sample problems that include integers and fractions. Practice problems available. [6:06]
