Exercise 8 Page 153

Start by using the Division Property of Equality.

14

Practice makes perfect
To solve the equation, we have to isolate b on one side. We will begin by dividing both sides by 3. This is allowed by the Division Property of Equality.
3b=42
b=42/3
b=14
Therefore, b=14 is the solution to the equation. To check that we have the correct solution, we can substitute b=14 into the original equation and simplify.
3b=42
3( 14)? =42
42=42
Since the left-hand side and the right-hand side are equal, b=14 is the correct solution.
