$x = 7$

$5x - 14 = 21$

We want to solve for the variable $x$ , so we have to make it alone and move everything else to the other side of the equation.

First, add $color(red)14$ to both sides of the equation:
$5x - 14 quadcolor(red)(+quad14) = 21 quadcolor(red)(+quad14)$

$5x = 35$

Now divide both sides by $color(red)5$ :
$(5x)/color(red)5 = 35/color(red)5$

Therefore,
$x = 7$

Hope this helps!
