Unit 4.2 - Systems of Equations
Big Ideas
In this unit you will focus on solving word problems by writing a pair of equations, called a system of equations. Then you will solve the system of equations with the same multiple representations. You will review how to solve an equation with the same multiple representations you used for solving linear equations: table graph and by manipulating the equations.
Along the way you will develop ways to solve different forms of systems and will learn how to recognize, when one method may be more efficient than another. By the end of this chapter, you will know multiple ways to find the point of intersection of two lines and will be able to solve systems that arise from different situations.
