See below

Step 1: $9 u - 16 = 20$ $9u-16=20$
First, you add $16$ $16$ to both sides.
$9 u = 36$ $9u=36$

Step 2: Now you need to divide both sides by $9$ $9$
So $\frac{9_{u}}{9} = \frac{36}{9}$ $9_u/9=36/9$

Step 3: $\frac{9_{u}}{9}$ $9_u/9$ is $u$ $u$ and $\frac{36}{9}$ $36/9$ is $4$ $4$ . So $u = 4$ $u=4$ .

The answer is $4$ $4$ .
