−5

−25

PLEASEEE! Include the steps you toke to get the answer.

Answer 1

Those are the answer choices btw

Answer 2

do you want the answer or help?

Answer 3

YOYO i got this

Answer 4

both?

Answer 5

I cant give you the answers...its against the code of conduct but i can help you...
first you need to distribute..do you know how to do that?

Answer 6

start by multiplying them out: 3(x+1) and -2(x-1)

Answer 7

ohk & yes
so it would be
3x+3=-2x-3-4 right?

Answer 8

correct now simplify it

Answer 9

by adding 2x on both sides right?

Answer 10

well yes but lets start with the addition and subtraction...
you would first subract -3-4

Answer 11

that would be -7

Answer 12

correct!

Answer 13

so 3x+3=-2x-7
now add 2x then subtract three on both sides?

Answer 14

now subtract the three on the left from the -7 on the right

Answer 15

and write it again

Answer 16

wait i think i distributed wrong with the -2x shouldnt it be -2x+2?

Answer 17

OH VERY GOOD! I want to say i was hoping you would pick up on that but i am sorry i missed it too

Answer 18

ohk :D

Answer 19

so now simplify 2-4

Answer 20

i got x=-1 right?

Answer 21

no... that is wrong..

Answer 22

;o crap

Answer 23

so far we have..
3x+3=-2x+2-4

Answer 24

lets try simplifying again

Answer 25

that would be 3x+3=-2x-2

Answer 26

correct...now subtract the three from both sides

Answer 27

3x=-2x+1

Answer 28

i think you did that wrong because your suppose to get them on one side

Answer 29

wait wait wait...i did nothing wrong...you added the three...you need to SUBTRACT it

Answer 30

dont worry girl...it will be done right bare with me

Answer 31

ohk so that would be
3=-5x-2?

Answer 32

now i add 2 and that equals
5=-5x divide that and its -1? right?

Answer 33

REWIND...FORGET THE X's JUST DO THE ADDITION...
3x+3=-2x-2
-3 -3
What do you get...NOT THE THREE X JUST THE POSITVE THREE

Answer 34

ps: im not yelling

Answer 35

ohk so thats 3x=-2x+5

Answer 36

no...its 3x=-2x-5

Answer 37

then do the x's

Answer 38

you need to know the order...when you get up into the geometry you will suffer if you dont learn this now!

Answer 39

order is PEMDAS right?

Answer 40

always move the addition and subtraction before you do the variables
PEMDAS is when you are solving a different equation...it is all addition and subtraction untill the end here...so first get the ones without the variable on one side then move the variable..

Answer 41

ohk but u still get -1 right? xD

Answer 42

so you subtract the three (not three x)from the negitive two and you get -5...now...do the variables and get them off to one side
KEEP UP WITH THE EQUATION...DONT JUMP AHEAD LOL

Answer 43

JUST DO THE STEPS

Answer 44

3X=-2X-5 what is next...get the -2x isolated on the other side...how do you do that?

Answer 45

yes the answer is -1...but i wanted you to do the steps not just tell me the answer..i wanted to make sure you grasped the consepts..

Answer 46

First look at the problem you want to tackle first. Lets tackle the equation ont he left first which is 3(x+1) distribute the 3. Now your problem should look like this: 3x+3. NOw lets do thesa me for the equation on the right side which is -2(x-1)-4 distribute -2. NOw your equations hould look like this: -2x+2-4.

Now the equations read:

3x+3=-2x+2-4

leave the left side alone at this point and lets focus on the right side once more. WE have -2x+2-4 subtract 2 from negative 4 now the equation should read -2x-2.

THe equation shouldr ead 3x+3=-2x-2
now add 2 to both sides like this:

3x+3=-2x-2
+2 +2
----------
5x+3=-2 this is now the equation

now subtract 3 from both sides like this
5x+3=-2
-3 -3
------------
5x=-5 now divide by 5
x= ?
you should be able to get your answer
