Question

Solve the compound inequality. Graph the solution
-2 ≤ 2x – 4 < 4

Answer 1

`-2 \ \textless \ = 2x - 4 \ \textless \ 4`


`-2+4\ \textless \ 2x\ \textless \ 4+4`
`Add \ 4 \ to \ the \ whole \ equation`


`2\ \textless \ 2x\ \textless \ 8`
`Simplify \ inequality`


`1\ \textless \ x\ \textless \ (8)/(2)`
`Divide \ the \ whole \ equation \ by \ 2`


`1\ \textless \ x\ \textless \ 4`
`= (1,4)`
