See the entire solution process below:

Step 1) Subtract $color(red)(30)$ from each side of the equation to isolate the $x$ term while keeping the equation balanced:

$4x + 30 - color(red)(30) = 30 - color(red)(30)$

$4x + 0 = 0$

$4x = 0$

Step 2) Divide each side of the equation by $color(red)(4)$ to solve for $x$ while keeping the equation balanced:

$(4x)/color(red)(4) = 0/color(red)(4)$

$(color(red)(cancel(color(black)(4)))x)/cancel(color(red)(4)) = 0$

$x = 0$
