$x = 12$ $x=12$

Move the variable to one side, and the constant to the other, to get
$2 x = 24$ $2x=24$
Then, divide both sides by 2 to get
$x = 12$ $x=12$

$x = 12$ $x=12$

$2 x - 9 = 15$ $2x - 9 = 15$

We wanna start by adding $9$ $9$ on both sides

$2 x - 9 + 9 = 15 + 9$ $2x - 9 + 9 = 15 + 9$

$2 x = 24$ $2x = 24$

Then divide both sides by $2$ $2$

$(cancel2x)/cancel2 = 24/2$

$x = 12$
