Exercise 38 Page 504

Use the Division Property of Equality to eliminate the multiplication.

Solution: x = 5
Graph:

Practice makes perfect

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 2. This will eliminate the multiplication and isolate x.

2x = 10

.LHS /2.=.RHS /2.

2x/2 = 10/2

Calculate quotient

x = 5

Let's mark x = 5 on the number line.
