See a solution process below:

Step 1) Subtract $8$ $color(red)(8)$ from each side of the equation to isolate the $n$ $n$ term while keeping the equation balanced:

$3 n + 8 - 8 = 17 - 8$ $3n + 8 - color(red)(8) = 17 - color(red)(8)$

$3 n + 0 = 9$ $3n + 0 = 9$

$3 n = 9$ $3n = 9$

Step 2) Divide each side of the equation by $3$ $color(red)(3)$ to solve for $n$ $n$ while keeping the equation balanced:

$\frac{3 n}{3} = \frac{9}{3}$ $(3n)/color(red)(3) = 9/color(red)(3)$

$(color(red)(cancel(color(black)(3)))n)/cancel(color(red)(3)) = 3$

$n = 3$
