You’ve learned three methods for solving a system of equations: Graphing, Substitution, and Elimination. Today in class, we talked about the characteristics of a system that might make one of the methods be easier than another, primarily using graphing when both equations are already solved for y (and fractions are involved), substitution when only one equation is already solved for one variable (x or y), and elimination when x and y are on the same side for both equations. Ultimately, though, you can use whatever method you want to solve, which is what I’m asking you to practice this weekend with Mixed Solving Method Review.
If you need graph paper, you can generate and print as many pages as you want here.
