#x=4#

Explanation:

#7x-6(8+7x)=-188#
By following PEMDAS (Parentheses, exponents, multiplication/division, addition/subtraction), first get rid of the parentheses by distributing the #-6# to the #(8-7x)#.
#7x-48-42x=-188#
Next, add 48 to each side to isolate the x terms on one side.
#7x-42x=-140#
Next, combine like terms on the left side of the equation,
#-35x=-140#
Finally, to isolate x on the left side, divide each side by #-35#.
#x=4#
