x + y = 20
x - y = 4
Add equations together and get:
2x = 24, and then divide by 2 to get
x = 12

plug in to the top 12 + y = 20
subtract 12 to get y = 8

so the 2 numbers are 12 and 8

The answer to your question is the numbers 12 & 8
The "difference" means to subtract one number from another
The "Sum" means to add two numbers together
12+8=20
12-8=4

Hope this helps! :)
