In this video we learn how to solve systems of equations with elimination / combination.

This is the first of two videos on solving systems of equations using the substitution method. Make sure to watch "Solving Systems by Substitution 2" for help with solving systems when both equations are in standard form!

This video practices solving systems of equations by substitution and elimination.

The elimination method is an algebraic method used to solve systems of equations. It simplifies two equations with two variables to one equation with one variable by getting opposite coefficients.

Systems of two linear equations in two variables can have a single solution, no solutions, or an infinite number of solutions. This chapter explains why.

Matrices are an important class of mathematical object used in many branches of mathematics, science and engineering. This lecture also introduces augmented matrices, a compact easy-to-manipulate representation of systems of linear...

In This Episode, Tyler Teaches Us About How to Solve Linear Equations by Elimination

In this video, the teacher explains the steps for solving systems of linear equations using elimination. The viewer is guided through examples and encouraged to check their work.

When should a system of equations with multiple variables be used to solve an Algebra problem, instead of using a single equation with a single variable?

Learn how to choose between elimination and substitution methods to solve a system of equations. This video provides examples and discusses the advantages and disadvantages of each method. The goal is to help students understand when to...
