Answer 1

Для решения данной системы уравнений, давайте следовать этапам:

1. Решим первое уравнение {2x•3 - 24 = 0: 2x•3 - 24 = 0 Упростим: 6x - 24 = 0 Добавим 24 к обеим сторонам уравнения: 6x = 24 Разделим обе стороны на 6: x = 24 / 6 x = 4

2. Теперь, когда мы знаем значение x, подставим его во второе уравнение {2y•3x - 54 = 0: 2y•3(4) - 54 = 0 2y•12 - 54 = 0 24y - 54 = 0 Добавим 54 к обеим сторонам уравнения: 24y = 54 Разделим обе стороны на 24: y = 54 / 24 y = 2.25

Таким образом, решение системы уравнений составляет: x = 4 y = 2.25
