Question

Which of the following is the saluting to the inequality 9+2x>5x? A. 2 B.3 c.4 d.8

Answer 1

x < 3

Explanation:

We are given an equation of inequality of single variable x.

So, we have to solve the inequality and get the solution in terms of another inequality.

The given equation is 9 + 2x > 5x

⇒ 9 > 5x - 2x

⇒ 9 > 3x

⇒ 3x < 9 {Since if a > b then we can write b < a as they means the same.}

⇒ x < 3 (Answer)

{Dividing both sides of an inequality with a positive number need no change in inequality sign}
