the heaviest human of all time weighed 486 kg this is 12 kg less than 6 times juans weight. how much does juan weigh?

math 
Chopsticks,
474=6x
X= 79 
math 
Reiny,
let Juan's weight be x kg
then 6x  12 = 486
6x = 498
x = 83
check: 6 times J's weight is 498
is 486 kg 12 less than 498 ? yes! 
math 
Quidditch,
Chopsticks is wrong.
let W = Juan's weight in kg
6W  12kg = 486kg
6W = 498kg
W = ? 
math 
Angela,
486 12 = 474
474 / 6 = 79
x= 79
