See a solution process below:

First, divide each side of the equation by #color(red)(5)# to eliminate the parenthesis while keeping the equation balanced:

#(5(m + 3.2))/color(red)(5) = 15/color(red)(5)#

#(color(red)(cancel(color(black)(5)))(m + 3.2))/cancel(color(red)(5)) = 3#

#m + 3.2 = 3#

Now, subtract #color(red)(3.2)# from each side of the equation to solve for #m# while keeping the equation balanced:

#m + 3.2 - color(red)(3.2) = 3 - color(red)(3.2)#

#m + 0 = -0.2#

#m = -0.2#

the answer is #m=-1/5#

distribute #5# to the inside equation
#5m+16=15#
subtract #-16# to both sides
#5m=-1#
divide by #5# to both sides
#m=-1/5#
