\_\_\_\_\_

Isolate variable term $\frac{u}{2}$ : Isolate the variable term $\frac{u}{2}$ by subtracting $4$ from both sides of the equation. $\newline$ $\frac{u}{2} + 4 - 4 = 5 - 4$
Simplify both sides: Simplify both sides of the equation. $\frac{u}{2} = 1$
Multiply by $2$ : Multiply both sides of the equation by $2$ to solve for $u$ . $\frac{u}{2} \times 2 = 1 \times 2$
Simplify to find $u$ : Simplify the equation to find the value of $u$ . $u = 2$
