That is the same as \((-11b-4)-(-b+3)[/tex}. Negatives are gross, so let's distribute it. Remember, that negative can be turned into a positive by changing the sign on every term in the parentheses. It's called distributing the negative. So we can change it to [tex](-11b-4)+(b-3)\). Now it's just basic addition.
\(-11b-4+b-3 = -10b-7\)
So your final answer is:
\(-10b-7\)
