Equations with a variable on both sides: video lessons
A lesson for 7th grade or pre-algebra students, where we look at linear equations with a variable on both sides. I actually start the lesson with a short review of how to combine like terms. Then we delve into the equations. The basic idea is to eliminate the term(s) with variable from one side, which then isolates those terms on the other side.
In the 2nd video, I go through a few more practice problems of equations where the variable is on both sides.
