Lesson Plan

Solving by substitution and elimination

Goals / Objectives

Solve a system of two linear equations by substitution or by elimination (including when scaling is required), choosing the method from the system's structure

Identify a solution to a system as an ordered pair satisfying both equations, the intersection point of the two lines

Answer a question that asks for a combination of the variables, such as x + y, obtaining it directly from the equations when their structure allows

Standards
