The solution set for the inequation -2x + 7 3, x ∈ R is : 1. {x : x ∈ R, x 2} 2. {x : x ∈ R, x 2} 3. {x : x ∈ R, x 2} 4. {x : x ∈ R, x 2}

Given, ⇒ -2x + 7 3 ⇒ 2x 7 - 3 ⇒ 2x 4 ⇒ x ⇒ x 2. Since, x ∈ R. Solution set = {x : x ∈ R, x 2} Hence, Option 4 is the correct option.

Given,

⇒ -2x + 7 ≤ 3

⇒ 2x ≥ 7 - 3

⇒ 2x ≥ 4

⇒ x ≥ $\dfrac{4}{2}$

⇒ x ≥ 2.

Since, x ∈ R.

Solution set = {x : x ∈ R, x ≥ 2}

Hence, Option 4 is the correct option.
