Exercise 58 Page 316

w=12

Practice makes perfect

To solve the equation, we have to isolate w on one side. Using the Division Property of Equality, we will divide both sides of the equation by 2. This will eliminate the factor and isolate w.

2w=24
2w/2=24/2
w=12

To check that this solution is correct, substitute w=12 into the original equation and simplify.

2w=24
2( 12) ? = 24
24= 24 ✓

Since the left-hand side and right-hand side are equal, w=12 is the correct solution.
