x in [23/24, 26/24)x[2324,2624)

Explanation:

You need to isolate xx between the two inequality signs. Start by adding 44 to all sides

-1/6 + 4 <= 4x - color(red)(cancel(color(black)(4))) + color(red)(cancel(color(black)(4))) < 1/3 + 4

23/6 <= 4x < 13/3

Now divide all sides by 4

23/6 * 1/4 <= (color(red)(cancel(color(black)(4)))x)/color(red)(cancel(color(black)(4))) < 13/3 * 1/4

This will get you

23/24 <= x < 13/12

which is equivalent to

23/24 <= x < 26/24

In interval notation, the solution set for this compound inequality is x in [23/24, 26/24).
