3. The Multiplication Property of Equality

4. Multiplication Property of Equality
If a = b, then a · c = b · c for any real numbers a, b, and c.
Example: Solve the equation 9x = 63.
· · 9x = · (Multiply both sides by )
1x= 7
x=7

5. Multiplication Property of Equality
Example: Solve the equation 8w = 3.
To solve the equation we divide both sides of the equation by 8.
8w = 3 =
w =
Divide both sides by 8.
