#b=-3#

Let's start by distributing the #-4# to both terms in the parenthesis.

Notice, we don't combine the #-3# and the #-4# because one of them is being multiplied. We now have:

#14-b=-3-8b-4#

We can simplify the terms on the right to get

#14-b=-7-8b#

Let's add #8b# to both sides to get

#14+7b=-7#

Let's subtract #14# from both sides to get

#7b=-21#

Lastly, dividing both sides by #7#, we get

#b=-3#

Hope this helps!
