  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.

  Gaussian Elimination. Another way to solve the original pair of equations is with Gaussian elimination. Start by picking a variable to eliminate. Let’s pick x to eliminate. Multiply the first equation by the coefficient of x in the second equation and multiply the second equation by the opposite of the coefficient of x in the first equation.

  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.
