#a=-2#

Explanation:

Given:
#color(white)("XXX")92=-6a-8(a-8)#
Expanding the right side
#color(white)("XXX")92=-6a-8a+64#
Combining like terms
#color(white)("XXX")92=-14a+64#
Subtracting #92# from both sides
#color(white)("XXX")=-14a-28#
Adding #(-14a)# to both sides
#color(white)("XXX")14a=-28#
Divide both sides by #14#
#color(white)("XXX")a=-2#
