See a solution process below:

First, add $color(red)(15)$ to each side of the equation to isolate the $x$ term while keeping the equation balanced:

$3x - 15 + color(red)(15) = -22 + color(red)(15)$

$3x - 0 = -7$

$3x = -7$

Now, divide each side of the equation by $color(red)(3)$ to solve for $x$ while keeping the equation balanced:

$(3x)/color(red)(3) = -7/color(red)(3)$

$(color(red)(cancel(color(black)(3)))x)/cancel(color(red)(3)) = -7/3$

$x = -7/3$
