3b+b because 3+1=4 just add b and replace 1 with b
b is the same as 1
3b is the same as 3

4b : b + 2(b + 2b) OR 3b + b

First option :

b + 2(b + 2b)

Simplify.

b + 2b + 4b

Simplify.

3b + 4b

Simplify.

7b

So, the first option is INCORRECT.

Second option :

3b + b

Simplify.

4b

So, our second option is CORRECT.

3b + b

~Hope I helped!~
