Answer by bobdabuildr(27)   (Show Source):
You can put this solution on YOUR website! You have two separate variables and two separate equations here.
the first one, the sum of two numbers is 35 is set up like x+y=35
the second one, the difference between the numbers is 13 is set up like x-y=13
What you need to do is add the second equation to the first equation and solve for x.
To write it on paper woul look like the x written over the x, y over y etc.
x+y=35
x-y=13
+______
2x =48 divide both sides by 2
x=24
To find y plug the answer for x back into either of the original equations and you will end up with 11.
Check
24+11=35
24-11=13
