Answer:
y represent the number of weeks
Step-by-step explanation:
Given expression
x - 2y
The veterinarian suggested that the overweight large-breed lose 2 pounds of its weight per week .
Let
x = initial weight
The overweight large-breed lose 2 pounds per week .
After first week of the weight loss
( x - 2)
The weight loss after one week = x - 2
The weight lost after 2 weeks
x - 2(2)
The weight lost after 2 weeks = x - 2(2)
The weight lost after y weeks
x - 2(y)
Where y = number of weeks
x - 2y
The weight lost after y weeks = x - 2y
Therefore, y represent the number of weeks
