#x=1#

Explanation:

#-48=-8(5-4x)-5(4x+4)#

Keeping in mind that the multiplication of two negatives makes a positive, and the multiplication of a positive and a negative makes a negative, open the brackets and simplify.

#-48=-40+32x-20x-20#

#-48=-60+12x#

Add #60# to each side.

#12=12x#

Divide both sides by #12#.

#1=x# or #x=1#
