1. **State the problem:** Simplify the expression $-(-526+-350)-150+74$.
2. **Rewrite the expression:** Note that $-(-a) = a$, so
$$-(-526+-350) = 526 + 350$$
3. **Calculate inside the parentheses:**
$$526 + 350 = 876$$
4. **Substitute back:**
$$876 - 150 + 74$$
5. **Perform subtraction and addition from left to right:**
$$876 - 150 = 726$$
$$726 + 74 = 800$$
6. **Final answer:**
$$\boxed{800}$$
