#x=17#

Identify like terms
#\color(red)(-28)\color(blue)(-5x)=\color(blue)(-8x)+\color(red)(23)#

Move like terms, then combine
#\color(blue)(-5x+8x)=\color(red)(23+28)#
#\color(blue)(3x)=\color(red)(51)#

#\thereforex=51/3=17#

#x=17#

First, you subtract the #23# from both sides;

#-51-5x=-8x#

Then, you add the #5x# to both sides;

#-51= -3x#

Finally, you divide both sides by #-3x#;

#x=17#
