Solution: Question 2. State, whether the following statements are true or false: (i) a < b, then a – c < b – c (ii) If a > b, then a + c > b + c (iii) If a < b, then ac > bc (iv) If a > b, then (v) If a – c > b – d, then a + d > b + c (vi) If a < b, and c > 0, then a – c > b – c Where a, b, c and d are real numbers and c ≠ 0. Solution: (i) a < b ⇒ a – c < b – c The given statement is true. (ii) If a > b ⇒ a + c > b + c The given statement is true. (iii) If a < b ⇒ ac < bc The given statement is false. (iv) If a > b ⇒ The given statement is false. (v) If a – c ...
