# How do you simplify 3b + 8 + 2b?

In your specific case, $b$ is just some number. For example if I have 6 lots of 4 in one hand and 3 lots of 4 in the other hand, I have 9 lots of four all together. The same logic applies here. How many lots of $b$ do you have altogether? Remember that the 8 is a constant, which doesn't affect the $b$ in any way.
The answer would be $5 b + 8$
