Elimination Lesson 2

Solving Elimination With Different Coefficients

4x - 9y = -9

x - 3y = -6

Example

• Can x or y multiply to match each other? If no cross multiply
  

• Does the letter I choose Have the same or opposite sign? If yes add a negative sign to one of the numbers

  being distributed
  

• Then multiply 1 or both equations
