Solving Equations With Variables on Both Sides of the Equal Sign

Today's lesson combines many of the topics we've worked on over the past two weeks and applies them to solving equations with the variable on both sides of the equal sign. Since our objective is to always isolate the variable, there will be paths to take to get to the solution. Students must guard against working too quickly, as this can lead to errors that will make the problems much harder than they really are. Examples of common errors include dropping negative signs, not distributing completely, or simple arithmetic errors.
