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, ....}
Solution
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, ....}.
