Khan Academy: Basic Linear Equation Word Problems

Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.

The sum of three consecutive odd integers is 231. What is the largest integer? See how to unpack this word problem, set up an equation, and solve for the variable.

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...

Combine several mathematics concepts as classes solve linear systems. After writing a system of equations involving a proportion, learners then solve the system. A video instructor uses the substitution method and must work...

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to more complex word problems.

Illuminate the world of mathematics for your class, specifically, the process of linear equations. In this video, Sal teaches about linear equations in standard form after two videos on slope-intercept and slope-point forms. He defines...

In this exercise, students practice linear equation word problems. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

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]

In this exercise, students practice solving systems of linear equations in word problems. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

This word problem is about two people who climb a wall. The formula is given for one and a table of values for the other and the problem asks who has the higher starting point, otherwise known as the initial value. [4:43]
