What is 3b + b + 6? Simplified

4b + 6

Step-by-step explanation:

Every variable that stands by it self is counted as one. 3b is 3b because it tells you. Since there's two "b" variables you add them together making 3b + b = 4b and since the 6 doesn't have a variable you don't add it to the 4b making your final answer 4b + 6

That simplified is 4b + 6
