#x =11#

#3x - 5 = 11x - 93#

#3x -11x - 5 = - 93#

#3x -11x = - 93 + 5#

#-8x = - 88#

#cancel(-)8x = cancel(-) 88#

#8x =88#

#x =88 ÷ 8#

#color(blue)(x =11#

Now we can substitute #x# for #11# to prove our answer.

#3x - 5 = 11x - 93#

#3 xx 11 - 5 = 11 xx 11 - 93#

#33 - 5 = 121 - 93#

#28 = 121 - 93#

#121 - 93 = 28#

#28 = 28#
