Exercise 40 Page 504

Use the Multiplication Property of Equality to eliminate the division.

Solution: x = 2
Graph:

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Multiplication Property of Equality, we will multiply both sides of the equation by 2. This will eliminate the division and isolate x.

x/2 = 1

MultEqn

LHS * 2=RHS* 2

x/2* 2 = 1* 2

FracMultDenomToNumber

a/2* 2 = a

x = 1* 2

MultByOne

a * 1=a

x = 2

Let's mark x = 2 on the number line.
