To find the numbers, you find the sum of two numbers as 60 and there difference is 24; Let X be the two integers and their sum as 60; the expression will be x - (60-x) = 24. Collect the like terms together and you will have 2x - 60 = 24. Divide both sides by 2 and the result will be x - 30 = 12, then substitute for x by add 30 to both sides; x= 42. Finally substitute the result and to get the other number; (60-x) = 60 ? 42. It will be 18. So the two numbers are 18 and 42.
