One of the numbers: x
The other number: y

Difference means subtract:
x-y=40

Sum means add:
x%2By=96

Add the two equations:
2x%2B0y=136

x=68

I'll let you calculate the other number.

x-y=40
x+y=96 now add.
-----------------
2x=136
x=136/2
x=68 answer.
68-y=40
-y=40-68
-y=-24
y=24 answer.
proof:
68+24=96
96=96
