For this case we have the following expressions:
[tex]2b + b\\3b[/tex]
For [tex]b = 1:[/tex]
[tex]2 (1) + 1 = 2 + 1 = 3\\3 (1) = 3[/tex]
For [tex]b = 2:[/tex]
[tex]2 (2) + 2 = 4 + 2 = 6\\3 (2) = 6[/tex]
For[tex]b = 3[/tex]:
[tex]2 (3) + 3 = 6 + 3 = 9\\3 (3) = 9[/tex]
For any number, the expressions will be equivalent because [tex]2b + b = 3b[/tex]
ANswer:
[tex](2b + b)[/tex]and [tex]3b[/tex] have the same value for b = 1,2,3
