Question

Check that 2b + b and 3b have the same value when b is 1,2, and 3

Answer 1

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`

For
`b = 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
