X + y = 27
      y = 27 - x

The numbers/addends are:
      x  and 27-x

Equation:
     (x) (27-x) = 92
 
     -x² + 27x = 92

Transform to quadratic equation form, ax² + bx + c = 0
     x² - 27x + 92 = 0

Solve the quadratic equation by factoring:
     (x-23) (x-4) = 0
 
     x - 23 = 0         x - 4 = 0
     x₁ = 23             x₂ = 4

ANSWER: The numbers are are  23 and 4.  

Check:

    23 + 4 = 27
  
    23  ×  4 = 92
