Substitution_method_for_systems_of_equations

Learn about the substitution method, which is another way to manipulate systems of equations in order to solve them.

Systems_of_equations_intro

Learn what "systems of equations" are, what counts as a solution to such a system, and how we can use graphs to solve them.

Elimination_method_for_systems_of_equations

Learn about the elimination method, which is a way to 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!

Solving_any_system_of_linear_equations

Use everything you learned so far in order to solve any kind of system of equations!
