$x = 0$

We have: $sin(x) + 3 = 3$

First, let's subtract $3$ from both sides of the equation:

$=> sin(x) + 3 - 3 = 3 - 3$

$=> sin(x) = 0$

Then, let's take the $arcsin$ of both sides:

$=> arcsin(sin(x)) = arcsin(0)$

$=> x = 0$

$x = kpi$

sin x + 3 = 3
sin x = 0
Unit circle -->
sin x = 0 --> x = 0, $x = pi$ , and $x = 2pi$
General answers:
$x = kpi$
