Answer:
In the first case x and y be 49 and 47 respectively
In the second case x and y be 41 and 37 respectively
Explanation:
Let us assume the two number be x and y
In the first case
Now
x + y = 96
x - y = 2
2x = 98
x = 49
y = 49 - 2 = 47
So x and y be 49 and 47 respectively
In the second case
x + y = 78
x - y = 4
2x = 82
x = 41
y = 78 - 41 = 37
So x and y be 41 and 37 respectively
