Exercise 34 Page 118

Use the Division Property of Equality to eliminate the multiplication.

x=6.5

Practice makes perfect

We are given the following equation. 6x=39 To solve the equation, we have to isolate x on one side. Using the Division Property of Equality, we will divide both sides of the equation by 6. This will eliminate the coefficient on the left-hand side of the equation and isolate x. Let's do it!

6x=39

.LHS /6.=.RHS /6.

6x/6=39/6

Cancel out common factors

6x/6=39/6

Simplify quotient

x=39/6

Calculate quotient

x=6.5

We found that x=6.5 is a solution to the equation.
