For the following inequation, represent the solution on a number line : 

3(2x -1) ≥ 2(2x + 3), x ∈ Z

Advertisements

Solution

3(2x -1) ≥ 2(2x + 3), x ∈ Z

⇒ 6x - 3 ≥ 4x + 6, x ∈ Z

⇒ 6x - 4x ≥ 6 + 3

⇒ 2x ≥ 9

⇒ x ≥ `9/2`

⇒ x ≥ `4 1/2`

∴ x = {5, 6, 7, ....}

  Is there an error in this question or solution?
