3.5/3.6 Linear Equations in Three Dimensions/Variables Day 4. 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 ...

There are many times in physics where you obtain 2 or more simultaneous equations. With 2 equations, you can solve for the unknowns by hand with reasonable care and you will probably not make a mistake. For example, you might solve the following equations with the substitution method. 3x – 2y = 7-4x + y = -6

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.
