***PLEASE HELP ASAPPPPPPPP, I WILL BECOME A FAN AND GIVE YOU A MEDAL*** This is from Algebra 2: Brad can make 4 key chains in an hour. Velma can make only 3 key chains in an hour, but she already has 6 completed key chains. Explain to Brad how he can use a system of equations to determine when he will have the same number of key chains as Velma.

well first Brad will have to determine the amount he has to chatch up to her them you can explian
anonymous
  • anonymous
yeah true
GreenCat
  • GreenCat
make equations B=4x V=3x+6 x is hours
anonymous
  • anonymous
ok so my teacher gave me 2 extra mins. gotta hurry up
GreenCat
  • GreenCat
just equate the 2 and solve for x
anonymous
  • anonymous
so basically i just need to plug all of this into words
GreenCat
  • GreenCat
4x=3x+6 solve
anonymous
  • anonymous
subtract 6 on both sides then divide by 3
GreenCat
  • GreenCat
nonono
GreenCat
  • GreenCat
subtract 3x from both sides
anonymous
  • anonymous
yeah lol my bad
anonymous
  • anonymous
and then ivide
GreenCat
  • GreenCat
it's faster
anonymous
  • anonymous
divide*
anonymous
  • anonymous
so basically what can i say
GreenCat
  • GreenCat
first subract and we'll see
anonymous
  • anonymous
ok so x = 6
GreenCat
  • GreenCat
aaand no need to divide now
anonymous
  • anonymous
yeah ik
anonymous
  • anonymous
how can i explain how brad used system of equations
anonymous
  • anonymous
u there?
GreenCat
  • GreenCat
The system of equations method is different.
GreenCat
  • GreenCat
just google it. I'm sure purplemath can help
anonymous
  • anonymous
here is the other part
GreenCat
  • GreenCat
You get the same answer.

Explain to Brad how he can use a system of equations to determine when he will have the same number of key chains as Velma.
anonymous
  • anonymous
hell no this isnt gonna help lmfao
GreenCat
  • GreenCat
Write the 2 equations: y=4x y=3x+6
GreenCat
  • GreenCat
Then see if you shuold subtract or add
anonymous
  • anonymous
yeah and we get 6
GreenCat
  • GreenCat
Subtract: y=4x minus y=3x-6
GreenCat
  • GreenCat
no
GreenCat
  • GreenCat
y=4x -y=-x-6 and add those two (I made the second one negative)
anonymous
  • anonymous
yeah
GreenCat
  • GreenCat
|dw:1433363403662:dw| I did part of it
GreenCat
  • GreenCat
now you do the rest. it's easy
anonymous
  • anonymous
dude.................................... y = 6...........................
anonymous
  • anonymous
x = 6
anonymous
  • anonymous
y=4x y=3x+6 4x = 3x + 6 -3 -3 x = 6
