Question

4 (x – 3) < x + 3, where x ∈ w

Answer 1

Answer:

x<5

Step-by-step explanation:

4x-12 < x+3

Adding (-x+12) to both sides, we get

3x < 15

x < 5

Hope this helps mate

Answer 2

Answer:

let it help you all

Step-by-step explanation:

We have 3x - 5 < 4

⇒ 3x - 5 + 5 < 4 + 5 (Add 5 to both sides)

⇒ 3x < 9

⇒ 3x/3 < 9/3 (Divide both sides by 3)

⇒ x < 3

So, the replacement set = {1, 2, 3, 4, 5, ...}

Therefore, the solution set = {1, 2} or S = {x : x ∈ N, x < 3}
