Question 363864
Let x = the smaller number
    y = the greater number

(y - x)/2 = 2
y - x     = 4     
        y = 4 + x      (1) 

y + 2x    = 13         (2)

Since y = 4 +x, eq. (2) becomes
(4 + x) + 2x = 13
          3x = 13-4
           x = 3
           y = 4 + 3
           y = 7

The numbers are 3 & 7
