What are the two numbers? math riddle - Two number equal 22 the difference between the two numbers is 4 What are the two numbers
 
let x and y be the numbers
x+y=22( i assume you have said sum of two nos. is 22)
x-y=4
adding the two equations we get 2x=26
=>x=13
put x=13 in the first equation and we get y=22-13=9
thus the two nos. are 13 and 9
