See the entire solution process below:

Step 1) Subtract #color(red)(8.2)# from each side of the equation to isolate the #a# term while keeping the equation balanced:

#2.4a + 8.2 - color(red)(8.2) = 5.2 - color(red)(8.2)#

#2.4a + 0 = -3#

#2.4a = -3#

Step 2) Divide each side of the equation by #color(red)(2.4)# to solve for #a# while keeping the equation balanced:

#(2.4a)/color(red)(2.4) = -3/color(red)(2.4)#

#(color(red)(cancel(color(black)(2.4)))a)/cancel(color(red)(2.4)) = -1.25#

#a = -1.25#
