1 3.2 Notes (part 2) Solving Systems Algebraically Elimination Objective: -solve systems using the elimination method -identify additive inverse -identify no additive inverse Solving Using Elimination Step 1: Check to see if two terms are additive inverses of one another. If so add the two equations. = + = - 3 2 7 2 4 y x y x Elimination Step 2: Solve for the remaining variable. Step 3: Substitute and solve for the other variable.
