$14 5/18$

Count the number of terms first and simplify each term separately.

$color(blue)((9 1/3 + 4 1/3) div 6)" "color(red)( - (-12))$

$=color(blue)((13 2/3) div 6)" "color(red)( +12)$

$=color(blue)(41/3 xx 1/6)" "color(red)( +12)$

$=color(blue)(41/18)" "color(red)( +12)$

$=color(blue)(2 5/18)" "color(red)( +12)$

$= 14 5/18$
