2< 2x< 6 i need solving this problem

2 < 2x < 6divide all 3 sections by 2

2/2 < (2/2)x < 6/2 =
1 < x < 3

or u can do it this way...split it
2 < 2x               2x < 6
2/2 < x               x < 6/2
1 < x                  x < 3

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
