$0$

Identify all the like terms and group them together:

$color(blue)(-11x) " "color(red)(+4)" " color(blue)(+8x)" " color(red)(-4" ") color(blue)(+3x)$

$=color(blue)(-11x)" " color(blue)(+8x)" " color(blue)(+3x)" "color(red)(-4)" " color(red)(+4)$

$=color(blue)(-11x) color(blue)(+11x) + color(red)(0)$

$=0$
