Lesson 7.2: Solving Systems of Equations Algebraically
Completion requirements
Graphically determining the solution to a system of equations is a
good visual method, but drawing graphs can take time, and usually the solutions are only approximations. Can a system of equations
involving quadratics be solved algebraically using the same methods
that worked for linear systems?
In Lesson 7.2, you will learn about
- solving systems of equations by substitution,
- solving systems of equations by elimination, and
- using systems of equations to solve problems.
