Number_of_solutions_to_equations

Linear equations can either have a single solution, infinite solutions, or no solutions. Learn how to determine the number of solutions to a given equation, and how to create equations with a desired number of solutions.

Equations_geometry

Solve problems in geometry by creating and solving appropriate linear equations.

Equations_with_parentheses

Learn how to solve linear equations with parentheses using the distributive property. For example, solve -9 - (9x - 6) = 3(4x + 6).

Equations_with_variables_on_both_sides

Learn how to solve linear equations that have the variable on both sides of the equation. For example, solve 2x+5=6x-3.

Equations_word_problems

Solve word problems by creating linear equations and solving them.
