*We can solve a system using substitution or elimination. It is best to use substitution if one equation is all ready solved for one variable, but elimination is best if both equations are in standard form. Examples: Solve the system of equations. If the system is dependent, express the solution set in terms of one of the variables.

Solve the system using eliminations to create a system of 2 equations with 2 variables. Solve that system using the methods we have used in this unit. Express your answer as an “ordered triple”. Example1: x + 2y – 3z = -2. 2x – 2y + z = 7. x + y + 2z = -4. Unit 3 Quiz 1 Review Day 5. Day 7 Determinants and Cramer’s Rule

The new system of equations consists of this new equation and either one of the other equations. Let's use the following for our equivalent system of equations. (Equivalent here means that the systems have the same solution.) = = We have now eliminated the x variable in the one equation. Solve for y by dividing both sides of that final equation ...

Solving Systems with Linear Combinations (“Elimination”): Sometimes solving a system of equations using substitution can be very difficult. For these problems we solve using Linear Combinations (or Elimination). With elimination you solve by eliminating one of the variables. This is accomplished by adding the 2 equations together.
