Answer:

21, 24

Step-by-step explanation:

1. Given:

  • [tex]xy=504[/tex]
  • [tex]x+y=45[/tex]
  • [tex]y=45-x[/tex]

2. Solution:

  • [tex]x(45-x)=504[/tex]
  • [tex]45x-x^2=504[/tex]
  • [tex]x^2-45x+504=0[/tex]
  • [tex]x^2-24x-21x+504=0[/tex]
  • [tex]x(x-24)-21(x-24)=0[/tex]
  • [tex](x-24)(x-21)=0[/tex]
  • [tex]x_1=24[/tex] ⇒ [tex]y_1=21[/tex]
  • [tex]x_2=21[/tex] ⇒ [tex]y_2=24[/tex]
