    The difference between two numbers is 19. Half the larger number plus twice the smaller number is 12. What are the numbers?

    This is the equation I came up with but I can’t make it work.
    x-y=19
    1/2x+2y=12 x2 –> x + 4y = 24
    ———-
    x – y = 19
    x +4y = 24
    ———— Subtract
    -5y = -5
    y = 1
    x = 20
