-6-3u+9-(-4u)
would you leave the -(-4u) as it is and combine the -4u with the -3u, or would you make the -(-4u) a positive 4u and then add it with the -3u?

-6-3u+9-(-4u)
You combine all the u terms and all the purely numeric terms.
The u terms are:
-3u - (-4u)
= -3u + 4u
= u
The numeric terms are:
-6 + 9
= 3.
Result: u + 3.

- 6 - 3u + 9 -(- 4u) = 0
- 6 - 3u + 9 + 4u = 0
u + 3 = 0
u = - 3

move like terms together, and the -(-4) becomes +4u
-6 + 9 - 3u + 4u
-3 + 1u
u-3
