Answer:

X=7

Y=10

Step-by-step explanation:

Replace expression Y=2x-4 in 17x + 36y = 479

  • 17x+36(2x-4)=479
  • 17x+72x-144=479
  • 89x-144=479
  • 89x=479+144
  • 89x=623
  • x=[tex]\frac{623}{89}[/tex]
  • x=7

Now, replace X=7 in expression Y=2x-4

  • Y=2(7)-4
  • Y=10

17x+36(2x-4)=479
17x+72-144=479
17x+72x=335
89x=335
x=3.76
