Check that 2b + b and 3b have the same value when b is 1,2, and 3
Misha Larkins [42]

For this case we have the following expressions:

2b + b\\3b

For b = 1:

2 (1) + 1 = 2 + 1 = 3\\3 (1) = 3

For b = 2:

2 (2) + 2 = 4 + 2 = 6\\3 (2) = 6

Forb = 3:

2 (3) + 3 = 6 + 3 = 9\\3 (3) = 9

For any number, the expressions will be equivalent because 2b + b = 3b

ANswer:

(2b + b)and 3b have the same value for b = 1,2,3
