Solving Systems of Equations by Elimination (Addition & Subtraction) **Basic Idea-You are subtracting/adding the 2 equations together to “eliminate” one of the variables. Ex. 1 2a + 4c = 30. 2a + 2c =21.5. Step 1 - Decide whether or not you would add or subtract. Remember that you are trying to eliminate one of the variables completely.

Substitution: solve one equation for a variable, substituting the expression you obtain into the second equation, then solving that resulting equation for a value, or . Elimination: add multiples of the equations together so that one of the variables is eliminated. Example: Solve . First, graph the equations.
