plz help me!

i told you i didnt get it!

what are you still confused about?

i just dont get it

do you know how to solve x - 2 = 3x + 4?

i just want to know how to solve it and have it explained it to me

|dw:1432753311665:dw|
what does that tell you about the two lines?

well, let's break it down step by step:
x - 2 = 3x + 4
what happens when you add 2 to each side?

i dont know what you mean
Do you mean:
2x-2=3x=6?

no, that's multiplication
ADD 2 to each side of the equal sign (+2)

x - 2 + 2 = 3x + 4 + 2
see how I added + 2 to each side?

yes

great! x - 2 + 2 = x, do you agree?

umm idk it doesnt look right because what did you do with the 3

yes i do

yes okay i am starting to get it a little bit

ok, now just look at the right side:
3x + 4 + 2
do agree that 3x + 4 + 2 = 3x + 6?

yes i do

awesome, now we put both sides together:
x = 3x + 6 but we're not done yet

what happens when you subtract 3x from each side?

would it become x=3x+3x+6?

remember how we added + 2 before? it's the same thing, except you SUBTRACT 3x instead of ADDING 2

would x= become -3x?

Not quite, what is x minus 3x?

3x

no, what is x - 3x?

easier question, what is 1 - 3?

-2

right! so what do you think x - 3x is?

are you saying that it is -2x?

6x?
3x+6=9x
9x-6x=(3x)?

I'm not sure where you're getting 9x
"subtract 3x" means minus 3 x
3x + 6 - 3x = ?

6x

no, please try again

easier question: what is a + b - a?

Right! so what is 3x + 6 - 3x?

2?

no, please try again...
easier question: what is 3x - 3x?

0x

right, and 0x is the same as 0, right?
so what is 3x + 6 - 3x?

|dw:1432755049920:dw|

IMPORTANT: 6 is NOT the same as 6x!
3x + 6 - 3x = 6, do you agree?

|dw:1432755224507:dw|

i dont get it i thought it was 6x

nope, it's just 6!
here is the original problem:
3x + 6 - 3x
see how 6 is in the middle?

or 6

yes

it's 6! REMEMBER: 6 is NOT the same as 6x

ohh okay!!!!

yes

can you solve for x now?

what does x = ?

x=-3

would that be 2y, -2y, 2, or -2

if it is even 2

y = x - 2 = (-3) - 2 = ?

-4

not quite, please check your math again

-3?

nope, please try again:
what is -3 - 2?

ohh -5

is it a or b
i thought it was b

YES, it's b.
(-3,-5) is where line A and line B intersect

that's what I meant by "solve for x" and "solve for y". It just means, find the value of x and y

omg thank you so much!!!!

no problem, I'm glad you get it now

thank you again you are amazing i gave you a metal and fanned you
