    First number is 6, second is 5

    Step-by-step explanation:

    What you have to do here is make a system of equations. X will be the first number, and y will be the second. With the first sentence, we can make the equation 4x + 8y = 64. The second sentence gives us 4x - y = 19. We can subtract these two equations to get 9y = 45. Quickly solving this we get y = 5. If we plug that in to the second equation, then we get 4x - 5 = 19. 4x = 24, then we solve that and get 6.
