Solve the inequation:
`-2 1/2 + 2x <= (4x)/5 <= 4/3 + 2x, x ∈ W`.
Graph the solution set on the number line.
उत्तर
`-2 1/2 + 2x <= (4x)/5 <= 4/3 + 2x`
`-2 1/2 <= (4x)/5 - 2x <= 4/3`
`-5/2 <= - (6x)/5 <= 4/3`
`25/12 >= x >= -10/9`
`2.083 >= x >= -1.111`
Since, x ∈ W
∴ Solution set = {0, 1, 2}
The solution set can be represented on number line as
