Purplemath: System of Equations Word Problems

In this video, Sal solves a word problem sent in by a listener with two cyclists riding towards each other over a given time. It is an interesting problem regarding ratios and the relationship between distance, rate, and time. He shows...

Here is a challenging motion problem about two different length trains and how long it takes them to pass each other going in the same direction and opposite directions. At first glance, there doesnÕt seem to be enough information given...

Sal evaluates a word problem and then solves by graphing systems of equations. This problem would be great as a daily challenge, as concept review, or as a homework assignment. Show this video only after the students have had a chance to...

Mix it up in math class! The video provides an equation hint to be able to setup mixture problems. Two problems are provided as examples on how to use the equation in order to solve mixture type word problems. 

This video demonstrates how to set up and solve a system of equations in order to solve a word problem concerning rates.

Learners solve eight short answer algebra word problems. They write and solve systems of equations in two or three variables given a word problem about integers, perimeter, consecutive numbers, etc.

Solve word problems by modeling them into a system of equations and solving it. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students explore two new scenarios that involve solving systems of equations. They will improve their understanding of how using mathematics to model a real-life situation with two variables can help them solve problems.

Students explore two real-life scenarios that involve solving systems of equations.

Learn how to solve problems by using systems of equations in this video. Explore how to solve real-world problems using this approach. [6:59]
