4x – 5y = 9 start by subtracting 4x from both sides

4x-5y=9-4x 5y=-4x+9 divide all by 5

1y=-0.8x+1.8

Yes? I'd like to see some input from you first.
mathmale
  • mathmale
Can you reduce your result further? 1y=-0.8x+1.8 Remember, the goal was to solve for y.
AlexandervonHumboldt2
  • AlexandervonHumboldt2
mistake pooja: 4x-5y=9 -5y=9-4x 5y=4x-9 divide both sides by 5 and solve
anonymous
  • anonymous
I can't think of any way to simplify that anymore
AlexandervonHumboldt2
  • AlexandervonHumboldt2
so you don't see anything that can be reduced?

1y=?

1.8 maybe
AlexandervonHumboldt2
  • AlexandervonHumboldt2
no
anonymous
  • anonymous
1y
AlexandervonHumboldt2
  • AlexandervonHumboldt2
no
AlexandervonHumboldt2
  • AlexandervonHumboldt2
remember: 1*a=a so wut is 1y=?

Hawaii: Why do you consider the "1" in front of that 'y' to be necessary?
anonymous
  • anonymous
1y=y
AlexandervonHumboldt2
  • AlexandervonHumboldt2
yes
anonymous
  • anonymous
And yes.
AlexandervonHumboldt2
  • AlexandervonHumboldt2
now what do you think the answer is? hint: 0.8=4/5 1.8=9/5
anonymous
  • anonymous
C.
AlexandervonHumboldt2
  • AlexandervonHumboldt2
yes finnaly!
