can you do the distributive part first?
FibonacciChick666
  • FibonacciChick666
(it will make the flow easier and I can check your work)

2x – 3y + 4xy + 5x

2x – 3y + 4(x – y) + 5x What you you get after you apply the distributive property to 4(x – y)?
Bossimbacon
  • Bossimbacon
but after that what property do I use? commumative, associative?
FibonacciChick666
  • FibonacciChick666
You did not distribute correctly
FibonacciChick666
  • FibonacciChick666
First thing, which is what Direct pointed out. So let's revisit that first
FibonacciChick666
  • FibonacciChick666
Do you understand the link?
Bossimbacon
  • Bossimbacon
oh so it would be 2x – 3y + 4x- 4y + 5x? @fibonaccichick666 @directrix
FibonacciChick666
  • FibonacciChick666
yea good
Bossimbacon
  • Bossimbacon
and then after what property would I use and could u show me
FibonacciChick666
  • FibonacciChick666
so now, what is our goal?
Bossimbacon
  • Bossimbacon
do I use associative property next? or commumative
FibonacciChick666
  • FibonacciChick666
well, first, what is our goal?
Bossimbacon
  • Bossimbacon
combine like terms? @FibonacciChick666
FibonacciChick666
  • FibonacciChick666
yea, so does commutative or associative allow you to move terms around?
Bossimbacon
  • Bossimbacon
commumative
FibonacciChick666
  • FibonacciChick666
(get all the like terms in one place is another way to say our goal)
FibonacciChick666
  • FibonacciChick666
Good! so, go ahead, make it so
Bossimbacon
  • Bossimbacon
so 2x - 4x + 5x+ 3y + 4y?
FibonacciChick666
  • FibonacciChick666
why is it -4x?
FibonacciChick666
  • FibonacciChick666
and +3y?
Bossimbacon
  • Bossimbacon
i dont know how to put it @FibonacciChick666
FibonacciChick666
  • FibonacciChick666
what do you mean? you just moved the terms around. You have to move the whole term, not just part of it
Bossimbacon
  • Bossimbacon
i dont understand.. how do you change it around? @FibonacciChick666
FibonacciChick666
  • FibonacciChick666
you literally just pick up term and move it. Like moving blocks on the floor when you were a kid. Let's say you had blue, red, yellow block. in that order, but you wanted red before blue, so you pick up the red block and move it in front of the blue or you pick up the blue bock and put it behind the red. Make sense? Now your blocks are terms (+4x or -4y etc) Just move them like you would blocks

2x – 4x + 5x- 4y + 3y?
Bossimbacon
  • Bossimbacon
@FibonacciChick666
FibonacciChick666
  • FibonacciChick666
did you have a -4x before you moved stuff around? Did you have a +3y?
Bossimbacon
  • Bossimbacon
+3y
Bossimbacon
  • Bossimbacon
@FibonacciChick666
FibonacciChick666
  • FibonacciChick666
What's that mean?
FibonacciChick666
  • FibonacciChick666
full sentences please. Or at least semi-full fragments
Bossimbacon
  • Bossimbacon
I had +3y @FibonacciChick666
FibonacciChick666
  • FibonacciChick666
I don't see a +3y, can you point it out? \[''2x – 3y + 4x- 4y + 5x?"\]
Bossimbacon
  • Bossimbacon
right after the 2x there's a 3y
FibonacciChick666
  • FibonacciChick666
I don't see a plus sign in front of it
Bossimbacon
  • Bossimbacon
oh its negative 3?
FibonacciChick666
  • FibonacciChick666
yea
FibonacciChick666
  • FibonacciChick666
commutative only works for addition so technically its +(-3y)
FibonacciChick666
  • FibonacciChick666
but so long as you bring the negative along for the ride, that's too many symbols to write all the time
Bossimbacon
  • Bossimbacon
so what is i t 2x + 4x- 5x 4y -3y? @FibonacciChick666
Bossimbacon
  • Bossimbacon
or could just explain it and right it down
FibonacciChick666
  • FibonacciChick666
this is your equation : \[2x – 3y + 4(x – y) + 5x=2x – 3y + 4x –4 y + 5x\] Now starting from there. Move the +5x to a better spot
Bossimbacon
  • Bossimbacon
2x + 5x?
FibonacciChick666
  • FibonacciChick666
you have to write the whole thing, you can't just leave off the rest
Bossimbacon
  • Bossimbacon
2x + 5x + 4x - 4y - 3y?
FibonacciChick666
  • FibonacciChick666
multiple steps, but yes
Bossimbacon
  • Bossimbacon
so the equation is right?
FibonacciChick666
  • FibonacciChick666
not simplified yet, but correct to this point
Bossimbacon
  • Bossimbacon
so added up it becomes 11x - 1y? @FibonacciChick666
FibonacciChick666
  • FibonacciChick666
what's a negative plus a negative?
Bossimbacon
  • Bossimbacon
a positive
Bossimbacon
  • Bossimbacon
11x1y?
FibonacciChick666
  • FibonacciChick666
no... thats times not addition
FibonacciChick666
  • FibonacciChick666
what is -6+-7
Bossimbacon
  • Bossimbacon
-14?
FibonacciChick666
  • FibonacciChick666
close, that would be -7+-7
Bossimbacon
  • Bossimbacon
-13 * sorry lol
FibonacciChick666
  • FibonacciChick666
I thought it might be a type-0
FibonacciChick666
  • FibonacciChick666
so what is -4y-3y
Bossimbacon
  • Bossimbacon
but isnt this subtracting not adding?
FibonacciChick666
  • FibonacciChick666
aka -4y+-3y
FibonacciChick666
  • FibonacciChick666
There is no such thing as subtraction or division actually
Bossimbacon
  • Bossimbacon
it wouldbe -7y
FibonacciChick666
  • FibonacciChick666
there we go
FibonacciChick666
  • FibonacciChick666
so final answer is?
Bossimbacon
  • Bossimbacon
11x - 7y?
FibonacciChick666
  • FibonacciChick666
yep
FibonacciChick666
  • FibonacciChick666
