Solving_equations_by_graphing_Algebra_2_level_
Learn how to approximate the solution to any equation by using the power of graphs.
Solving_systems_of_equations_with_substitution
Learn about the substitution method, which is another way to manipulate systems of equations in order to solve them.
Analyzing_the_solutions_to_systems_of_equations
Learn how to determine the number of solutions a system of equations has, without having to go through the entire solution process.
Learn how to make the most out of the familiar algebraic techniques in order to solve systems of three equations with three variables.
Equivalent_systems_of_equations_and_the_elimination_method
Learn about the elimination method, which is a way manipulate systems of equations in order to solve them algebraically. This is actually very similar to the way we manipulate single equations in order to solve them!
The_possible_number_of_solutions_of_systems_of_linear_equations
Learn about the possible number of solutions of systems of linear equations. Spoiler: There can be a single solution, zero solutions, or infinite solutions. These different cases define the distinctions between "consistent" and "inconsistent" systems, and between "dependent" and "independent" systems.
Introduction_to_systems_of_linear_equations
Learn what "systems of equations" are, what counts as a solution to such a system, and how we can use graphs to solve them.
Systems_of_linear_equations_word_problems
Now that we are able to solve any kind of system we are given, it's time to use that knowledge to solve some word problems.
Solving_any_system_of_linear_equations
Use everything you learned so far in order to solve any kind of system of equations!
