Here's ur answer dear :)
_______________________
y = 151 - x
y = x^(1/2) + 19
151 - x = x^(1/2) + 19
x^(1/2) = 132 - x
x = x^2 - 264x + 132^2
x^2 - 265x + 17424 = 0
(x - 144)(x - 121) = 0
Solutions:
x = 144, y = 7
x = 121, y = 30
The numbers are 144 and 7 or 121 and 30
The value of the greater number minus
the lesser number is either 137 or 91.
Thanks for the question!!
