$u=122$

First, what you want to do is get the numbers and variable (the letter u) on opposite sides of the equation.

Subtract 228 on both sides of the equation to get $u$ by itself like this:

$106 =228 - u$
$-228 -228$

On the left side of the equation you get $-122$ because $106-228 = -122$ , and on the right side you are just left with $-u$ because $228-228 =0$ .

Now you're left with:

$-122 = -u$

Next, we have to divide both sides by $-1$ to make $u$ positive. The minus signs drop out since the numerator and denominator are both negative.

$(-122)/(-1) = (-u)/(-1)$

Therefore, $u=122$
