Let the numbers be x and y
x-y=12.........1
x+y=10........2
Adding 1 and 2
x+y+x-y=12+10
2x+y-y=22
2x=22
x=11
y=x-12=11-12=-1
Therefore, the numbers are -1 and 11

We have taken the numbers as X and Y. We know that difference between then is 12. Therefore, x-y=12 OR x-12=y. We also know that their sum is 10. Therefore, x+y=10
We have added these two. x-y=12 and x+y=10. We get x-y+x+y=12+10. Now, we add like terms together
thank you for your answer
x+x=2x and y+(-y) =y-y=0
Therefore, 2x+0=12+10
2x=22, or, x=11
Again we know that x+y=10
11+y=10
y=10-11
y=-1
