To find the value of the expression \(5c - 4b\), substitute the given values for \(c\) and \(b\):

\[
5c - 4b = 5(-3) - 4(2)
\]

Now, calculate each part:

1. \(5(-3) = -15\)
2. \(4(2) = 8\)

Substitute these results back into the expression:

\[
5c - 4b = -15 - 8 = -23
\]

So, the value of \(5c - 4b\) is **-23**.
