Let x be the larger number and y be the smaller one. We have two variables and two equations as follows:
therefore 2x=26 and x=13 and y=21-13=8. The two numbers are 8 and 13.
let x equal the number you are looking for. The second number the instructions say there is a difference of 5 between these tow numbers and when you add them together you get 21
So x= one number
and x-5 = second number
now, add these together to get 21
(x+x)-5= 21
now solve algebraically and you'll have your answer
