- How do you solve systems of equations using elimination?
- What is the elimination method for solving systems of equations?
- How do you solve the system 3x + 5y = 14 and 2x - 5y = 1 using elimination?
- How can you get rid of x or y in a system of equations?
- How do you know which variable to get rid of and whether to add or subtract in elimination?
- How do you solve for the other variable when solving a system of equations using elimination?
- How do you solve the system 6x + 2y = 8 and 6x - 4y = -10 using elimination?
This video tutorial does a great job of explaining how to eliminate a variable in a system of equations. However, not only does the video not go through and solve for the other variable, but both examples done are rather easy. No manipulation is necessary to get rid of a variable; adding or subtracting is sufficient to eliminate one of them.
