Answer:
Jerry's weight is 36kg and tom's weight is 66kg
Step-by-step explanation:
According to the given condition:
Let,tom's weight =x
Jerry's weight=y
So,
X=2y-6 ---(1)
X+y=102-----(2)
Put value of x from eq 1 in 2
2y-6+y=102
3y-6=102
3y=102+6
3y=108
Y=108/3=36
Jerry's weight is 36.
Put value of y in eq 1
X= 2(36) -6
X=72-6
X=66
So, Tom's weight is 66kg
