Math, microeconomics or criminal justice
sum = 23
difference = 18
22 and 1 don't work for the difference
try
21 and 2 have a difference of 19
20 and 3 have a difference of 17
you need the average of 21 and 20 as one number
20.5 and 2.5 sum to 23 and their difference is 18
x+y=23
x-y = 18 add to get
2x = 41
x = 41/2 = 20.5
y = 20.5-18 = 2.5
