Systems of Equations and Inequalities Review

Which is not a method for solving a system of equations?

• Graphing

• Fundamental Theorem of Arithmetic

• Substitution

• Elimination

Using elimination, what is the correct first step to solve this system of equations?

x-2y=3 and x+2y=6

• Add the 2 equations together

• subtract the 2 equations
