The Subtraction Property of Equality says that if a equals b, which statement must also be true for any number c?

1. The Subtraction Property of Equality allows the same quantity to be subtracted from both sides of an equation without changing whether it is true. 2. If a equals b, subtracting c from a and from b keeps both sides equal to each other. 3. Subtracting c from only one side, or multiplying both sides instead, would not preserve the equality in the same way. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 2 "The Language of Algebra", section 2.3 Solving Equations Using the Subtraction and Addition Properties of Equality_
