Thank you some much john!
nice post, john
The sum is 15 so... x + y = 15 and their difference is 7 so... x - y = 7
Your choices are substitution (where you re-arrange equation 1 for x or y... and sub it into equation 2). Or elimination where you add up equation 1 and 2, in elimination the y's zero out and you have 2x = 22, so divide by 2 and x = 11. Once you have x sub it back into either equation and solve for y.
