#a=2#

Explanation:

#1#. Since the bases are the same on both sides of the equation, the exponents are equal to each other. We can represent this relationship using an equation.

#6^color(blue)(-2a)=6^color(orange)(2-3a)#

#color(blue)(-2a)=color(orange)(2-3a)#

#2#. Solve for #a#.

#-2a# #color(red)(+3a)=2-3a# #color(red)(+3a)#

#color(green)(a=2)#
