#m=-6#

#2 = 11 + 3m + 9#

#3m = 2 - 11 - 9#

#3m = -18#

#m = -6#

#m=-6#

#2 = 11 + 3(m +3)#

Start by distributing

#2 = 11 + (3)(m)+(3)(3)#

#2 = 11 + 3m + 9#

#2 = 3m + 20#

Then flip the equation

#3m + 20 = 2#

Subtract #20# on both sides

#3m + 20 - 20 = 2 - 20#

#3m = -18#

Divide both sides by #3#

#(cancel3m)/cancel3 = (-18)/3#

#m=-6#
