📐 System of Equations: topic_systems_unique_solution_title

A system of equations is a collection of two or more equations with the same set of unknown variables (such as $x$ and $y$). Solving the system means finding the values for the variables that make all equations true at the same time.

The two most common algebraic methods are **Substitution** (solving one equation for a variable and substituting it into the other) and **Elimination** (multiplying and adding/subtracting the equations to cancel out one of the variables).
