Question

If 5x − 3 < 10 and 1 − 2x < −7, then solution set is:

विकल्प

• No solution

• x < 2 `3/5`

• x > 4

• `13/5 <x<2`

Answer 1

No solution

Explanation:

5x − 3 < 10

⇒ 5x < 13 

⇒ x < `13/5`

1 − 2x < −7

⇒ −2x < −8

⇒ x > 4

These require `x < 13/5 (2.6)` and x > 4 simultaneously, which is impossible.
