Lisa has a new puppy. The puppy weighs 5 pounds less than one-third the weight of Lisa's dog. Together, the dog and the puppy weigh 31 pounds. Which system of
equations could be used to find the weight of each animal?
A y=1/3x - 5
с
= 3x + 5
y = x + 31
y = x + 31
By={x-5
Dy= 1x + 5
y = -x + 31
y = -x + 31
