Question

The solution set of 4x – 3 ≤ 5, where x ∈ N, is ______.

Options

• {1}

• {1, 2}

• {0, 1, 3}

• none of these

Answer 1

The solution set of 4x – 3 ≤ 5, where x ∈ N, is {1, 2}.

Explanation:

Given,

⇒ 4x – 3 ≤ 5

⇒ 4x ≤ 5 + 3

⇒ 4x ≤ 8

⇒ `x ≤ 8/4`

⇒ x ≤ 2

Since, x ∈ N

⇒ Solution set = {1, 2}
