Web30 jan. 2024 · To find, the value of x and y = ? Multiplying equation (2) by 3, we get 3 (3x - y) = 3 (19) ⇒ 9x - 3y = 57 ......... (3) Adding equations (1) and (3), we get 2x + 3y + 9x - 3y = 53 + 57 ⇒ 11x = 110 ⇒ x = ⇒ x = 10 Put x = 10 in equation (1), we get 2 (10) + 3y = 53 ⇒ 20 + 3y = 53 ⇒ 3y = 53 - 20 ⇒ 3y = 33 ⇒ y = ⇒ y = 11 ∴ x = 10 and y = 11 Web4 jun. 2024 · If 2x - 3y = 79 and x + 6y = 47, then the value of (x - y) is- Q7.

As the value of [x-y] is to be obtained so put this value of x = 9 and y = -1 the value of [x-y] is determined. ⇒ [x-y] = [9 - (-1)] = 9 + 1 = 10. Hence, the obtained value of [x-y] is 10. So, the correct option is (c). bankverbindung zart
