Algebraic Intersection of Linear functions
This topic is also referred to as solution of simultaneous equations.
- Two equations in two unknowns:
- There are two algebraic methods for solving a set of two equations involving two variables
- Substitution method: we substitute one variable from one equation into the other
- Elimination method: we eliminate one variable and form one equation
- Three equations in three unknowns: For a set of three simultaneous equations involving three variables, the elimination method is the only practical procedure.
