Х=4

У=4

Z=4

Подставляем эти значения и все сходится

Сначала 12 разделить на 3 и понимаем что это равно 4, то есть 4+4+4=12.

Затем 4 в квадрате равно 16, то есть 16+16+16=48.

Ну и последнее понятно думаю

$4 + 4 + 4 = 12 \\ {4}^{2} + {4}^{2} + {4}^{2} = 48 \\ 3 \times 4 - 2 \times 4 - 4 = 12 - 8 - 4 = 0$
