Answer 1

Hello!

Let's solve by distributing. 

$13(b + 1) - 6 - 3b - 5 13b + 13 - 6 - 3b - 5$

Now we add/subtract like terms. 

$13b + 13 - 6 - 3b - 5 13b + 7 - 3b - 5 13b + 2 - 3b 10b + 2$ 
Your final equation is $10b + 2$, which cannot be simplified further, making it our final answer. 

Hope I helped! :3
