#x=-6.9#

Divide both sides by #3#

#-6.9=(3(x+4.6))#

#-6.9/3=(3(x+4.6))/3#

#-2.3=x+4.6#

Subtract both sides by #4.6#

#-2.3-4.6=x+4.6-4.6#

#-6.9=x+0#

#-6.9=x#

Alternatively, begin by distributing #3# each term in #x+4.6#

#-6.9=3(x+4.6)#

#-6.9=3x+13.8#

Subtract #13.8# from both sides:

#-6.9-13.8=3x+13.8-13.8#

#-20.7=3x+0#

#-20.7=3x#

Divide both sides by #3#:

#-20.7/3=3/3x#

#-6.9=x#

the answer is #x=-6.9#

first distribute #3# to the inside equation. then subtract #13.8# with #-6.9# then divide by #3#
