Step-by-step explanation:
-2 = -(x-8)
-2 = -x + 8 ( - * + = - and - * - = + )
-2 - 8 = -x +8 - 8
-2 - 8 = -x
-(2+8) = - x
-10 = -x | * (-1)
x=10
I just found 10% of it, which is 14, then found 5% of it through the previous work, which is 7
then i multiplied 7 by 11, because 55/5 is 11, so 55% of 140 is 77
