Answer:
y-x=22
Step-by-step explanation:
If Alice had started at zero, and she measured her belt to be 22 inches long
End Point- start point= 22
22-0=22
Let x be the starting point of measurement
Let y be the ending point of measurement
It means therefore that: y-x=22
Her two points will be values of x and y that satisfies the equality
y-x=22.
E.g. If y=28, x=6
28-6=22. These are possible endpoints.
However, if y=27, x=6
y-x=27-6=21
These are not possible endpoints.
