We will be presented with a real world situation where two friends are shopping the same store for a game system and video games. We will define variable terms to represent the cost of each. We will write two linear equations, one for each of the friends that represent their individual purchases. We will solve the system of linear equations using elimination since one pair of like terms as the same coefficient. We will subtract each pair of like terms. We will then evaluate one of the original equations using the value for the variable by substituting. We will then solve for the second unknown variable. We will answer the question using the information. An exemplar solution is modeled and explained.\n
