Exercise 72 Page 314

Start by using the Addition Property of Equality.

q=27

Practice makes perfect

To solve the equation, we have to isolate q on one side. We will begin by adding 3 to both sides. This is allowed by the Addition Property of Equality.

q/3-3=6

LHS+3=RHS+3

q/3-3+3=6+3

Add terms

q/3=9

Now that the q term is isolated, we will use the Multiplication Property of Equality to eliminate the coefficient 13.

q/3=9

LHS * 3=RHS* 3

q/3*3=9*3

FracMultDenomToNumber

a/3* 3 = a

q=9*3

Multiply

q=27
