To solve the expression $5\sqrt{3} - 5\sqrt{6} + 2\sqrt{3} - \sqrt{6}$, we'll combine like terms.

Step 1: Combine the terms with $\sqrt{3}$

$5\sqrt{3} + 2\sqrt{3} = (5 + 2)\sqrt{3} = 7\sqrt{3}$

Step 2: Combine the terms with $\sqrt{6}$

$-5\sqrt{6} - \sqrt{6} = (-5 - 1)\sqrt{6} = -6\sqrt{6}$

Step 3: Write the final expression

$7\sqrt{3} - 6\sqrt{6}$

So, the final answer is $\boxed{7\sqrt{3} - 6\sqrt{6}}$.
