Linear_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.

Two_step_equation_word_problems

Learn how to set up and solve equations to find answers to real-world questions.

Linear_equations_with_parentheses

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

Why_we_do_the_same_thing_to_both_sides_of_an_equation

A high-level, conceptual walk-through of what an equation represents and why we do the same thing to both sides of it

One_step_addition_subtraction_equations

Solve equations by adding and subtracting numbers from both sides.

One_step_multiplication_division_equations

Solve equations by multiplying and dividing numbers from both sides.

Analyzing_the_number_of_solutions_to_linear_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.

Two_steps_equations_intro

Learn how to solve equations like 2x+7=13 and 3(x+4)=3, which can be solved in two steps.

Linear_equations_word_problems

Solve word problems by creating linear equations and solving them.

Linear_equations_with_unknown_coefficients

An equation like ax+3x=bx+5 can still be solved for x even though some of the coefficients are variables.

Algebraic_equations_basics

Explore what it means for equations with variables (algebraic equations) to be solved.
