Best Answer

In algebra, when you have the expression "3b + b," you can simplify it by combining like terms. In this case, the like terms are both terms with the variable "b." So, 3b + b is equal to 4b. This is because you are adding the coefficients (3 and 1) together while keeping the variable "b" the same.
