Answer 1

Пошаговое объяснение:

$1) \: \: 19x = 95 \\ x = \frac{95}{19} = > x = 5 \\ \\ 2) \: \: x \times 22 = 132 \\ x = 132 \div 22 \: \: = > x = 6 \\ \\ 3) \: \: 38x - 16x = 1474 \\ (38 - 16)x = 1474 \\ 22x = 1474 \\ x = 1474 \div 22 = 67 \\ \frac{1474 \: \: \: | \: 22 }{132 \: \: \: \: \: \: | \: 67} \: \\ \: \: \: 154 \: \\ \: \: \: 154\ \\ \: \: \: \: \: \: \: \: 0 \\ 4) \: \: y + 27y = 952 \\ 28y = 952 \\ y = \frac{952}{28} < = > y = 34\\ \\ 5) \: \: \frac{x}{25} = 16 \: < = > x = 16 \times 25 \\ x = 400 \\ \\ 6) \: \: \frac{324}{x} = 27 \: \: < = > \: x = \frac{324}{27} \: < = > \\ x = 12$
