By declaring that the given equation is not valid; since $\left(- 0.5 - 1.8 = - 2.3\right)$

#### Explanation:

Perhaps this was intended to be:
$\textcolor{w h i t e}{\text{XXX}} - 0.5 x - 1.8 = - 3.3$
In which case:
$\textcolor{w h i t e}{\text{XXX}} - 0.5 x = - 1.5$
$\rightarrow \textcolor{w h i t e}{\text{XXX}} x = 3$
