Solve 1/x + 1/y = 9 and 1/x - 1/y = 3 |
|
Answer» Answer: Step-by-step explanation: Let 1/x = a and 1/y = b Given, ⇒ a + b = 9 ⇒ a = 9 - b In other equation: ⇒ a - b = 3 ⇒ ( 9 - b ) - b = 3 { from above, a = 9 - b } ⇒ 9 - b - b = 3 ⇒ 9 - 2b = 3 ⇒ 9 - 3 = 2b ⇒ 6 = 2b ⇒ 6 / 2 = b ⇒ 3 = b Therefore, ⇒ a = 9 - b = 9 - 3 = 6 Hence, a = 1 / x = 6 ; x = 1 / 6 b = 1 / y = 3 ; y = 1 / 3 |
