$x = 10$

$3x - 7 = 23$

To solve for $x$ we have to make $x$ alone, so let's move everything else to the other side of the equation.

First, add $color(red)7$ to both sides of the equation:
$3x - 7 quadcolor(red)(+quad7) = 23 quadcolor(red)(+quad7)$

$3x = 30$

Now divide both sides by $3$ :
$(3x)/color(red)3 = 30/color(red)3$

$x = 10$

Hope this helps!
