Answer 1

Let's solve the equations step by step.

1. Start with the first equation:

\[
4b + 15 + 8 = -13
\]

Combine like terms on the left side:

\[
4b + 23 = -13
\]

2. Next, we subtract 23 from both sides to isolate the term with \( b \):

\[
4b + 23 - 23 = -13 - 23
\]

This simplifies to:

\[
4b = -36
\]

3. Now, divide both sides by 4 to solve for \( b \):

\[
b = \frac{-36}{4}
\]

This simplifies to:

\[
b = -9
\]

So, the solution is:

\[
b = -9
\]
