Linear Systems (Chapters 4 & 5)
Lesson 5: Solve Linear Systems by Elimination (5.3)
Video 1: Introduction to Solving Linear Systems by Elimination
Video 2: Solve Linear Systems by Adding or Subtracting Equations
"Add" when both variable terms to be eliminated have "opposite" signs!
"Subtract" when both variable terms to be eliminated have "same" signs!
Video 3: Solve Linear Systems by Elimination - Adding Equations
"Add" when both variable terms to be eliminated have "opposite" signs!
Video 4: Solve Linear Systems by Elimination - Multiple and Add
First multiply to get a common coefficient for one of the variable terms.
Then "add" when both variable terms to be eliminated have "opposite" signs!
Video 5: Solve Linear Systems by Elimination - Subtracting Equations
"Subtract" when both variable terms to be eliminated have "same" signs!
Video 6: Solve Linear Systems by Elimination - Multiple and Subtract
First multiply to get a common coefficient for one of the variable terms.
Then "subtract" when both variable terms to be eliminated have "same" signs!
Video 7: Solve Linear Systems by Elimination (How to present steps)
It's always a good practice to label your equations and steps!
