Ответ(ы) на вопрос:
2Y - X = - 7 X = 2Y + 7 X^2 = (2Y+7)^2 = 4Y^2 + 28Y + 49 ............................. X^2 - Y^2 = 24 4Y^2 + 28Y + 49 - Y^2 = 24 3Y^2 + 28Y + 25 = 0 D = 784 - 12*25 = 784 - 300 = 484 V D = 22 Y1 = - 28 + 22 \ 6 = - 6\6 = - 1 Y2 = - 50\6 = - 25\3 = - 8 1\3 .......................... X = 2y + 7 X1 = - 2 + 7 = 5 X2 = - 50\3 + 21\3 = - 29\3 = - 9 2\3
