#x=7/12#

#x-19=-12-11x#

Add #19# to both sides to get
#x=7-11x#

Add #11x# to both sides to get
#12x=7#

Divide both sides by #12# to get
#x=7/12#

Hope that helps!
Happy mathing!

#x=7/12#

The equation is #x-19=-12-11x#.

Move all like terms to one side; all the terms with #x#'s to one side and just numbers to the other.

#x-19=-12-11x=>#

#x-19color(blue)(+19)color(red)(+11x)=-12color(blue)(+19)-11xcolor(red)(+11x)=>#

#xcolor(red)(+11x)=-12color(blue)(+19)=>#

#12x=7=>#

#x=7/12#
