Solving Systems by Elimination
TEKS Aligned: A5C
This is a double-sided notes page with 8 systems of linear equations written in standard form that can be used for in-class notes to teach solving systems by the elimination method.
The examples are written so that the odds can be teacher led and the evens can be in-class guided practice. Each even number applies the same concept to solve the system as the odd number that precedes it. Each example is written in a larger font so that it is easier for students to work with.
In addition, when using multiplication with the elimination method, I teach students to move across the page instead of down the page. This keeps the like terms lined up (and this is why the examples are on the far left of the page). If an equation does not need to be multiplied by anything, then it is just copied down. (This is shown in the key).
The 4 examples on the front can be solved by either adding or subtracting straight down. The 4 examples on the back will need multiplication to either one or both equations. The front could be used as notes one day and then the back another. Key included. This document was updated on 3/7/15 to be a double-sided notes page.
