this looks super easy to me but for some reason i'm confused. I think i'm over thinking it.
(a) Solve the inequality (b) Graph the solution set (c) Write the solution set using interval notation -1 < 1/2(x+3) < 2?

Assuming that should be shown as :-
- 1 < (1/2) (x + 3) < 2
- 2 < x + 3 < 6
- 5 < x < 3
Sol. set is { x : - 5 < x < 3 , x Є R }
- 1 < (1/2) (x + 3) < 2
- 2 < x + 3 < 6
- 5 < x < 3
Sol. set is { x : - 5 < x < 3 , x Є R }
