Let us start with the expression:
$$
\left(7 u^{2}+9 u\right)-\left(7 u^{2}+4 u\right)
$$

**Step 1: Distribute the subtraction.**

Subtracting the second expression from the first gives:
$$
7 u^{2} + 9 u - 7 u^{2} - 4 u
$$

**Step 2: Combine like terms.**

Group the $$u^{2}$$ terms:
$$
7 u^{2} - 7 u^{2} = 0
$$

Group the $$u$$ terms:
$$
9 u - 4 u = 5 u
$$

**Step 3: Write the simplified expression.**

Thus, after combining like terms, the simplified expression is:
$$
5 u
$$
The simplified expression is $$5u$$.
