$\huge\bf { \red A \green N \pink S\blue W \orange E \purple R \green{...}}$

$\longrightarrow \sf \dfrac{x}{3} + 3 = 45 \\ \\ \longrightarrow \sf \frac{x + 9}{3} = 45 \\ \\ \longrightarrow \sf x + 9 = 45 \times 3 \\ \\\longrightarrow \sf x +9 = 135 \\ \\\longrightarrow \sf x = 135 - 9 \\ \\\longrightarrow \boxed{ \sf x = 126}$
