Question

If x ∈ W, then the solution set of the in equation 5 – 4x ≤ 2 – 3x is ______.

Options

• {…, – 2, – 1, 0, 1, 2, 3}

• {1, 2, 3}

• {0, 1, 2, 3}

• {x : x ∈ R, x ≤ 3}

• {3, 4, 5, ....}

Answer 1

If x ∈ W, then the solution set of the in equation 5 – 4x ≤ 2 – 3x is {3, 4, 5, ....}.

Explanation:

x ∈ W    ....(Given)

5 – 4x ≤ 2 – 3x

⇒ 5 – 2 ≤ – 3x + 4x

⇒ 3 ≤ x

As, x ∈ W, thus the solution set is {3, 4, 5, ....}.
