The document defines algebraic concepts like equations, inverse operations, and properties that can be used to solve equations. It provides examples of true, false, and open equations and shows how to solve different types of equations using inverse operations, commutative and identity properties, and subtraction rules.

5. An Equation is like a balance scale. Everything must be equal on both sides. 10 5 + 5 =

6. When the amounts are equal on both sides it is a true equation. 12 6 + 6 =

7. When the amounts are unequal on both sides it is a false equation. 8 2 + 2 =

8. When an amount is unknown on one side of the equation it is an open equation. 7 n + 2 =

9. When you find a number for n you change the open equation to a true equation. You solve the equation. 7 n + 2 = 5
