See a solution process below:

First, group and combine like terms on the left side of the equation:

$2x + 3x + 4 = 29$

$(2 + 3)x + 4 = 29$

$5x + 4 = 29$

Next, subtract $color(red)(4)$ from each side of the equation to isolate the $x$ term while keeping the equation balanced:

$5x + 4 - color(red)(4) = 29 - color(red)(4)$

$5x + 0 = 25$

$5x = 25$

Now, divide each side of the equation by $color(red)(5)$ to solve for $x$ while keeping the equation balanced:

$(5x)/color(red)(5) = 25/color(red)(5)$

$(color(red)(cancel(color(black)(5)))x)/cancel(color(red)(5)) = 5$

$x = 5$
