The given expression is:

\[
7\sqrt{7} + 2\sqrt{7} - 5\sqrt{7} - 3
\]

Let's simplify this step-by-step:

1. Combine like terms involving \(\sqrt{7}\):
   \[
   (7 + 2 - 5)\sqrt{7}
   \]
   Simplify the coefficients:
   \[
   4\sqrt{7}
   \]

2. Now include the \(-3\):
   \[
   4\sqrt{7} - 3
   \]

So, the simplified answer is:

\[
4\sqrt{7} - 3
\]
