Studdy Solution
Solve the equation for $u$.
First, simplify the denominator:
$$4 = \frac{-2 - u}{2}$$
Multiply both sides by 2 to eliminate the fraction:
$$8 = -2 - u$$
Add 2 to both sides to isolate $u$:
$$8 + 2 = -u$$ $$10 = -u$$
Multiply both sides by -1 to solve for $u$:
$$u = -10$$
The value of $u$ is:
$$u = \boxed{-10}$$
