Question

–2 ≤ 2x – 4 < 4

Answer 1

@Nieta add 4 to all the sides
\[-2\le 2x-4<4\]
\[-2+4\le 2x-4+4<4+4\]
what would you get?

Answer 2

Case I

–2 ≤ 2x


-1 <=x


Case II

2x – 4 < 4

2x < 8

x < 4


Combining

-1 <=x< 4

Answer 3

divide the whole by 2

-1<=x-2<2

add 2 on both sides

-1+2<=x-2+2<2+2

1<=x<4
x lies in b/w [1,4)
