What is the Division Property of Equality?

Back

If a = b, then a/c = b/c for any non-zero c. Example: If 2x = 14, then x = 14/2 = 7.

What is the Addition Property of Equality?

Back

If a = b, then a + c = b + c for any c. Example: If x - 3 = 6, then x = 6 + 3 = 9.

What is the Subtraction Property of Equality?

Back

If a = b, then a - c = b - c for any c. Example: If x + 4 = 10, then x = 10 - 4 = 6.
