  1. Solving systems of equations algebraically

  2. Objectives Content Objectives Students will learn the elimination/addition for solving systems of equations algebraically. Language Objectives Students will participate in discussion. Students will ask and answer questions.

  3. The Addition/Elimination Method • If necessary, multiply one or both of the equations by a constant so that one of the variables can be eliminated by addition. • Add the equations formed in step 1. • Solve the equation formed in step 2. • Substitute the value found in step 3 into either of the original equations and solve.

  4. elimination 3x + 2y = 1 - 3x + 3y = 24

  5. Elimination - 2x - 4y = 30 2x - 5y = 51

  6. Elimination 3x - 3y = - 12 3x + y = 16

  7. elimination 2x + 4y = 28 - 4x + 2y = 4
