The multiplicative property of equality is a mathematical principle that states that if two numbers are equal, then their product with any third number is also equal. In other words, if a = b, then for any real number c, a * c = b * c. This property allows us to manipulate equations and solve problems more easily.

## Multiplicative Property Of Equality With Examples

- Start with the equation x = y.
- Multiply both sides of the equation by a non-zero number z, let’s say z = 2.
- Applying the multiplicative property of equality, we get: x * 2 = y * 2.
- Simplifying both sides, we get: x * 2 = 2y.
- Thus, using the multiplicative property of equality, we were able to isolate y on one side of the equation and obtain a new equation in terms of x.

The multiplicative property of equality can be used in several ways, including:

- Solving equations: By using the property, one can isolate a variable on one side of the equation and solve for it.
- Simplifying expressions: By using the property, one can simplify complex expressions by eliminating common factors or grouping terms.
- Proving equalities: The property can be used to prove equalities between expressions or numbers.
- Transforming expressions: The property can be used to transform one expression into an equivalent expression that is more convenient to work with.
- Verifying solutions: The property can be used to verify that a solution to an equation is correct by substituting the solution back into the equation and seeing if both sides are equal.
