After completing this tutorial, you'll know what a linear equation is and how to solve one using various arithmetic properties. Contains several definitions, problems with step-by-step solutions, and practice exercises. Includes links to...

This task presents a straight forward question that can be solved using an equation in one variable. The numbers are complicated enough so that it is natural to set up an equation rather than solve the problem in one's head. Aligns with...

Construct an equation or an inequality that models a given context. Modeling expressions can be quadratic, rational, or exponential. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video,...

After solving one system of equations by the methods of graphing, elimination using addition or subtraction, elimination using multiplication, and substitution, learners will be given four systems to be solved by one of each of the four...

For this task, students are shown the graphs of two equations, with areas bounded by their lines and intersections shaded in different colors. They are asked to write a system of equations or inequalities for each shaded area and explain...

For this problem, students must determine how much quinoa and how much corn are in a type of pasta. They must study the ingredient list which shows the protein content of the pasta. They know that quinoa has more protein than corn and...
