Question

Given x ∈ {whole numbers}, find the solution set of: -1 ≤ 3 + 4x < 23

Solution

`-1  <= 3 + 4x < 23`

`=> -1 <=  3 = 4x`   and  3 + 4x < 23

`=> -4 <= 4x`  and  4x < 20

`=> x >= -1`  and x  < 5

`Since x in {"Whole number"}`

∴ Solution set = {0, 1, 2, 3,4}

  Is there an error in this question or solution?
