Since x and y must be positive, 7x and 11y are positive either. That means 7x + 11y > 0. Then we would obtain N > 0 because 7x + 11y = N. That also means N must be positive. So if we set N to be zero or negative, there would be no solution. Thus, to produce an answer of No solution, the highest number N could be is 0.
For these kinds of questions you should first solve for x:
y +36 = x^2 ⇒ √y+36 = x
now the inverse of this equation is:
√x + 36 = y :)))
i hope this is helpful
have a nice day
