Sure, let's solve this step by step:

1. First, distribute the negative sign in the second parentheses: -(−7−4a) becomes +7+4a.

2. Now, the equation becomes: (−9+8a) + (7+4a).

3. Combine like terms: -9 + 8a + 7 + 4a.

4. This simplifies to: 12a - 2.

So, the solution to the equation "(−9+8a)−(−7−4a)" is "12a - 2".
