Modeling equations with a pan balance

Math

I explain the basics of how we model simple equations with a pan balance (scales). Each side of the balance represents one side of the equation. The two sides are EQUAL (weigh the same). The 2nd part of this lesson is here: In it, we look at examples with several unknowns on one side. See more math videos for 5th grade: Math Mammoth 5th grade curriculum:

In these equations, we need to remove some unknowns (x's) or some amount ("weight") from both sides -- or do both. Using the scales (pan balance) as a visual model will help you see this principle! When the same amount is removed from BOTH sides, the balance will stay balanced -- which means we can still write the equals sign between the expressions.

There are several unknowns (x's) in one pan in the balance or scales (on one side of the equation). What to do? It is simple! The last part of this lesson is here: In it, you will learn to remove the same amount of weight or unknowns from both sides of the equation.
