Решите уравнение:
-4 ( -2 (-4y+7 ) +4 ) -4 = 2 ( -2 (-4y + 7) + 8

СРОЧНО!!!!

-4*(-2*(-4y + 7) + 4) - 4 = 2*(-2*(-4y + 7) + 8-4*(8y - 14 + 4) - 4 = 2*(8y - 14) + 8-32y + 56 - 16 - 4 = 16y - 28 + 836 + 20 = 48yy = 56/48y = 1 1/6Проверим:-4*(-2*(-4*7/6 +7) + 4) - 4 = 2*(-2*(-4*7/6 + 7) + 8-4*((28/3 - 14) + 4) - 4 = 2*((28/3 - 14) + 8-112/3 + 56 - 16 - 4 = 56/3 - 28 + 8-37 1/3 + 36 = 18 2/3 - 2036 + 20 = 37 1/3 + 18 2/356 = 56Ответ: {1 1/6}
