Exercise 19 Page 160

Apply inverse operations to isolate w.

10.5

Practice makes perfect

To solve the given equation for w, we will use the Properties of Equality to apply inverse operations on the equation. Remember, only like terms can be combined.

2w+33=54

LHS-33=RHS-33

2w+33-33=54-33

Subtract terms

2w=21

.LHS /2.=.RHS /2.

2w/2= 21/2

Calculate quotient

w=10.5

The width is 10.5.
