Chapter 2 - Systems of Linear Equations and Inequalities - 2.3 Solving Systems of Equations Using the Elimination Method - 2.3 Exercises - Page 161: 34

We can use the elimination method here. We multiply one of the equations by a factor that will make one variable the same in both equations but differing in sign only. We can then add the equations together, thus eliminating one variable and leaving the other to be solved.
