See the entire process below:

Step 1) Subtract $color(red)(3)$ from each side of the equation to isolate the $m$ term while keeping the equation balanced:

$-3/4m + 3 - color(red)(3) = 8 - color(red)(3)$

$-3/4m + 0 = 5$

$-3/4m = 5$

Step 2) Multiply each side of the equation by $color(red)(-4)/color(blue)(3)$ to solve for $m$ while keeping the equation balanced:

$color(red)(-4)/color(blue)(3) xx -3/4m = color(red)(-4)/color(blue)(3) xx 5$

$cancel(color(red)(-4))/cancel(color(blue)(3)) xx color(blue)(cancel(color(black)(-3)))/color(red)(cancel(color(black)(4)))m = -20/3$

$m = -20/3$
