What numbers when multiplied equals 1800 but when adding equals 105

Let x = first number
     y = second number
 
(1) xy = 1800

(2) x + y = 105
           y = 105 - x
we will substitute y to the first equation

(1)              (x)(105 - x) = 1800
  
 
Using formula
a = 1, b = -105, c = 1800
= x





(2) x + y = 105
we'll substitute x = 83.43
   83.43 + y = 105
               y = 105 - 83.43
               y = 21.57

Therefore, the two numbers are 83.43 and 21.57

        

Oh yeah yeah the answer is oh yeah yeah
