Let 'x' be one of the numbers
      'y' be the other number
----------------------------------
-the sum of two numbers is 15 
x + y = 15     -----equation 1
------------------------
-three times one of the number is 19 less than 5 times the other
3y = 5x - 19       -------equation 2
------------------------
From equation 1
x + y = 15
x = 15 - y    ---equation 1'
-----------------------
Substitute equation 1' to equation 2
3y = 5x - 19
3y = 5(15-y) - 19
3y = 75 - 5y - 19
Transpose -5y to the left side of the equation
3y + 5y = 75 - 19
8y = 56
y = 7
-------------------
Substitute y=7 to equation 1'
x = 15 - y
x = 15 - 7
x = 8
------------------
Therefore the two numbers are 7 and 8.
