wait nevermind forget that
anonymous
  • anonymous
let's do this easier
anonymous
  • anonymous
i got it but how like when you distribute 3 to 2/3 you multiply 3x2 and then 3x3 ??
anonymous
  • anonymous
|dw:1333500868601:dw|
anonymous
  • anonymous
this is the correct
anonymous
  • anonymous
now when you multiply 2/3 by 3 you get 2

  • anonymous
you simplify them, got it?
anonymous
  • anonymous
ohh its like illiminating ?
anonymous
  • anonymous
so you have 2x
anonymous
  • anonymous
yeah, it's like cancelling
anonymous
  • anonymous
soo its 2x+9=21 ?
anonymous
  • anonymous
nope, beware
anonymous
  • anonymous
you have to multiply 2/3 times 9

anonymous
  • anonymous
it's equal 6
anonymous
  • anonymous
oooh , okaay i get it the answer would bee 2x+6=21 ?
anonymous
  • anonymous
yeah you got 2x + 6 = 21 now you have to solve for x. but did you understand how we got 6?
anonymous
  • anonymous
yess because 2x3 is 6 right ?
anonymous
  • anonymous
yeah. did you get the part where we simplified by diving 9/3 and 3/3? that's equal 3 and 1
anonymous
  • anonymous
so we had 2*3/1 which is 6/1 (same as 6)
anonymous
  • anonymous
yess i got it :D thank you soo much melinda
anonymous
  • anonymous
welcome. do you know how to solve for x?
anonymous
  • anonymous
yeah i know that part
anonymous
  • anonymous
