Art of Problem Solving: Solving Linear Equations Part 3

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

I'm a fan of clearing the denominator, but solvers can also find common denominators and cross multiply to solve the linear equations on the instructional activity. Each of the six problems has rational coefficients.

Eliminate the obvious. A series of slides presents algebra classes with step-by-step procedures for solving systems of equations using the elimination method. It provides an introduction to the elimination method for...

On problems 5-8 of the practice SAT video series (page 424 of The Official SAT Study Guide), Sal demonstrates several different ways to solve each problem in an efficient and timely manner. Students will appreciate the ways he details...

Adding the values of angles, deciphering fraction word problems, and solving complex linear equations are all in a day's work for Sal, who will stop at nothing to help your students pass the SAT. His clear annotations and strong...

Learners build skills for writing and solving equations with a video that describes the process for writing expressions and then an equation to solve a problem. The problem asks for the number of nickels and dimes needed given a set of...

Your classes will be cashing in on this lesson! A well-designed lesson describes the steps of solving for the number of two different coin types given specific information. Although some may write equations using two variables, the...

How much is that jingling worth? Given information on the relative number of nickels and quarters, along with their total value, scholars learn to set up and solve a linear equation to find the actual number of each type of coin. A short...

Another method for solving systems of equations, in addition to graphing, is the focus of this video, as Sal demonstrates the substitution method. It's important to understand that there is more than one way to solve any problem,...

School subjects connect when your young scholars use math to edit English. Math allows you to convert an entire paragraph into a simple equation or inequality. Examples encourage learners to write expressions, equations, and inequalities...
