Exercise 13 Page 59

Apply inverse operations to isolate b.

b=a/3 -3

Practice makes perfect

To solve the given literal equation for b, we will use the Properties of Equality to apply inverse operations on the equation.

a=3b+9

LHS-9=RHS-9

a-9=3b

.LHS /3.=.RHS /3.

a/3 -3=b

Rearrange equation

b=a/3 -3
