Question

Solve the following inequalities and represent the solution graphically on number line:

3x – 7 > 2(x – 6), 6 – x > 11 – 2x

Sum

Solution

3x – 7 > 2(x – 6)

⇒ 3x – 7 > 2x – 12

⇒ 3x – 2x > – 12 + 7

⇒ x > –5    …(1)

6 – x > 11 – 2x

⇒ –x + 2x > 11 – 6

⇒ x > 5    …(2)

From (1) and (2), it can be concluded that the solution set for the given system of inequalities is `(5, ∞)`. The solution of the given system of inequalities can be represented on number line as
