Answer 2

-2<2x-4<10

Answer 3

@凯旋小灰 How did you get that?

Answer 4

just added together

Answer 5

7>x>1

Answer 6

I do not know is that right or not.
I just think when 2x – 4 > -2 and 2x – 4 < 10,
move-2 to another side,is -2<2x-4,
so -2<2x-4<10.

Answer 7

Answer 8

yes, then take off the -4 is 2<2x<14,
make 2x to x,is 1<x<7.

Answer 9

and please be attention that smaller one should put left,and bigger one on right .

Answer 10

2x - 4 > -2 add 4 to both sides

2x > 2 so x> 1

and

2x - 4< 10

2x < 14 so x < 7

so I'd write it as

1 < x < 7

Answer 11

the solution is saying that the value of x is between 1 and 7

Answer 12

and also 1 and 7 are not included..
