Question

Help

8 – 3x – x = 12

x =

Answer 1

Okay m8 so you have to isolate the numbers from the equation and solve for x.

Answer 2

so what do you do?

Answer 3

add 8 on both sides?

Answer 4

no subtract since 8 is positive

Answer 5

oh

Answer 6

yes then what do you do?

Answer 7

I got 4 so the equation looks like this now? 3x-x=4

Answer 8

No lol you forgot the
-3x -x = 4
-4x = 4
x = -1

8 was positive all along but 3x was negative since the minus sign was in front of it.

Answer 9

3x + -x?

Answer 10

Do you get it? If not let me know and if you have anymore questions just tag me and I will try my best to help you.

Answer 11

wait what? the question said
8 - 3x -x = 12
so you isolate the x which means you subtract 8 on both sides which leaves you with
-3x - x = 12 - 8
then you combine like terms
-4x = 4
then solve for x
x = 4/-4
x = -1

Answer 12

how did you get the negative sign?

Answer 13

at which part? I just copied what your question said

Answer 14

-3x - x = 12 - 8

Answer 15

ohhh you mean how did I get -4x?
-3x -x = -4x
because when you add two minus signs together you get a negative answer
-8 because you subtracting it from the 12 side

Answer 16

you subtracted it on both sides right?
8 = 12
-8 -8
_____ ______
0 4

Answer 17

yeah, which comes out to 3x-x=4?

Answer 18

no you still have
-3x -x = 4
-4x => since negative + negative = negative answer

Answer 19

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

Answer 20

I know but how did you get the negative sign? Once subtracting from both sides minus 8 cancels out

Answer 21

right?

Answer 22

or am I missing something

Answer 23

Yes on the left side not on the right side

Answer 24

Whatever you do on the left you have to do the same thing on the right hence why you are subtracting 8 from 12 on the right side

Answer 25

right, so that comes out as 4

Answer 26

yes

Answer 27

but you still have to solve for X and you still have
-3x - x = 4
so you have to do next is
combine like terms => -4x = 4
then you divide the -4 on both sides which gives you
x = -1

Answer 28

wait so if I subtracted -8 from both sides like this, 3x -8-x=12
-8 -8

it'd come out as positive?

Answer 29

but if I did it on the right side 8 - 3x - x =12

it would be negative?

Answer 30

YES lol

Answer 31

Ohhh

Answer 32

I am so confused wait what's the question?

Answer 33

The real one so i can see whether what you are talking cause that matters a lot

Answer 34

???? \[8-3x-x=12\]

Answer 35

it's been 20 minutes ;-;

Answer 36

okay that's the question right?

Answer 37

yes.

Answer 38

Dude you keep messing me up and the answer is a negative answer

Answer 39

I was just wondering why it was a negative number instead of positive -_-

Answer 40

Well that's because you are dividing it by a negative number

Answer 41

dividing? where did that come from

Answer 42

well sorry I tried to explain it clearly m8 don't get all grumpy at me :p sorry if i came off rude

Answer 43

-4x = 4
x = 4 / (-4) = - 1

Answer 44

ok well thanks for the help

Answer 45

sorry if i confused you dude sorry

Answer 46

it's fine, I didn't think you were rude at all

Answer 47
