The sum of two numbers is 29 and their difference is 5. find the numbers

So what do you know


x+y=29
and
x-y=5

So you now have two equations to play with..

Just rewrite your two sentences as equations:

"The sum of two numbers is 29" ---> x + y = 29

"their difference is 5" ---> x - y = 5


Now just solve those two simultaneous equations. Do you know how to do that?
