Please help!! I'm very confused

b+7

Step-by-step explanation:

To simplify an equation, you combine like terms and remove redundancies. Like terms are 4b and 3b, another pair of like terms are 9 and 2. Let's combine them. 4-3 is 1, so we can make the equation into 1b+9-2. We can simplify that to b+9-2. But wait, we can combine 9 and 2. 9-2 is 7, so the final simplified equation is b+7. I hope this helps!
