Question

How do I do this problem? It's asking me this..
Solve: -1<2-3x<1

The answer can be written in form: A 14 years ago

Answer 1

a = -1
b = -1/3

Answer 2

-1<-2<-3x<1
A = -1
b=-1/3

Answer 3

Can you guys explain to me how you got that?

Answer 4

please

Answer 5

it said that x must be greater than A and it also must be less than B so you need to transfer the 2 from 2-3x to any side and devide both side by -3 to eliminate it from x,

Answer 6

the only thing you need to remember when you will transfer the 2 from 2-3x is that you must stisfy the given A<x<B

Answer 7

so if we transfer 2 to the left side and devided both sides by -3 it will be:

1< x <-1/3

but 1 is greater than -1/3 how can be x is greater than 1 but less than -1/3
so the only other option is to transfer 2 to the right to get the correct answer.

Answer 8

I put that answer in and it said it was wrong :( AHHHHH I don't get these !

Answer 9

the right answer is
a = -1
b = -1/3

Answer 10

1/3 < x < 1

Answer 11

I did that so the answer is positive or negative?

Answer 12

Ahhhh ! Since I got it from it gave me a new problem now!

Answer 13

Now it gave me 1<-2-5x<4

Answer 14

the answers were negative.

Answer 15

-1<2-3x<1
-1 - 2 < -3x < 1 - 2
-3 < -3x < -1
-3/-1 > -3x/-1 > -1/-1
3 > 3x > 1
3/3 > 3x/3 > 1/3
1 > x > 1/3
or 1/3 < x < 1

Answer 16

Can you help me with this problem because it gave me a whole new problem now :( ! 1<-2-5x<4

Answer 17

For 1<-2-5x<4, Ans. -6/5 < x < -3/5

Answer 18

-3/5 < x < -6/5

Answer 19

Solved similarly:
1<-2-5x<4
1+2<-5x<4+2
3<-5x<6
-3 > 5x > -6
-3/5 > x > -6/5
or -6/5 < x < -3/5

Answer 20

So which ones A and B?

Answer 21

Cus I have to put it in like that

Answer 22

smallest is typically indicated by the first variable as in (A,B); so A = -6/5 and B = -3/5

Answer 23

good

Answer 24

AHHHH I FREAKING LOVE YOU THANKYOUUUUU :)

Answer 25

np

Answer 26

hello,

i can tell u
it should be -1<-3x+2<1
-1-2<-3x<1-2
-3<-3x<-1
you derive it then to -3 and the position of < will come back to > because you have derived it to a negative one.
so:

1>x>1/3\[\rightarrow\]
1/3<x<1
a=1/3
b=1
