Answer:
The numbers are 49 and 55
Explanation:
The sum of two numbers 104
x+y = 104
their difference 6
x-y = 6
Add the two equations together to eliminate y
x+y = 104
x-y = 6
------------------
2x = 110
Divide by 2
2x/2 =110/2
x = 55
x+y = 104
55+y =104
Subtract 55 from each side
55-55+y = 104-55
y =49
