Exercise 64 Page 343

What do you need to do to obtain x=14 from x2=7?

Multiplication Property of Equality

Practice makes perfect

Let's examine the given statement and determine the property that justifies the statement. If x/2=7, then x=14.

In order to obtain x=14 from x2=7, we multiply both sides of the equation by 2. x/2 * 2=7 * 2 ⇒ x=14 Therefore, Multiplication Property of Equality justifies this statement. If a=b, then a * c=b * c.
