$u = - 3 \frac{1}{2}$ or $- 3.5$

#### Explanation:

$\frac{u}{2} - 3 \frac{1}{4} = - 5$

The first thing we should do is add $3 \frac{1}{4}$ to both sides of the equation. So $- 5 + 3 \frac{1}{4} = - 1 \frac{3}{4}$
$\frac{u}{2} = - 1 \frac{3}{4}$

Now to solve $u$, we multiply both sides by $2$:
$u = - 3 \frac{1}{2}$ or $- 3.5$

The common denominator is $4$. However, you do not need a common denominator in this problem as shown above.

Hope this helps!
