   # Homework 4 solving systems by elimination day 2 answer key

One student in the pair will solve the system by addition and the other by substitution. After solving, each pair of students should compare the answers and methods used with each other. Question 2 asks to state which method was easier to use and why. In this case, addition is probably the easier way to the solution, but it's always interesting to hear what students that chose substitution have to say. The idea is to teach students how the way a system is written can lend itself to one solving method better than another.  ## Systems of Equations: Elimination Method (Day 2)    ## Go Math Grade 8 Answer Key Chapter 8 Solving Systems of Linear Equations – Go Math Answer Key

We have solved systems of linear equations by graphing and by substitution. Graphing works well when the variable coefficients are small and the solution has integer values. Substitution works well when we can easily solve one equation for one of the variables and not have too many fractions in the resulting expression. The third method of solving systems of linear equations is called the Elimination Method. When we solved a system by substitution, we started with two equations and two variables and reduced it to one equation with one variable. The Addition Property of Equality says that when you add the same quantity to both sides of an equation, you still have equality. We will extend the Addition Property of Equality to say that when you add equal quantities to both sides of an equation, the results are equal.   ### Teacher Webpages
