Systems of Equations and Inequalities Practice Test

Directions: In some of the following problems, you will be asked to find quantities such as x + 2 y for a system of equations. Solve the system and put the solution in the formula. For example, if the solution is x = 3 and y = 5, then x + 2 y becomes 3 + 2(5) = 13.
