Answer 1

Ответ:

$1) \: 3x + 5x + 96 = 1568 \\ 8x + 96 = 1568 \\ 8x = 1568 - 96 \\ 8x = 1472 \\ x = 1472 \div 8 \\ x = 184$

$2y + 7y + 78 = 1581 \\ 9y + 78 = 1581 \\ 9y = 1581 - 78 \\ 9y = 1503 \\ y = 1503 \div 9 \\ y = 167$

$3) \: 88880 \div 110 + x = 809 \\ 808 + x = 809 \\ x = 809 - 808 \\ x = 1$

$4) \: 357y - 149y - 1843 = 11469 \\ 208y - 1843 = 11469 \\ 208y = 11469 + 1843 \\ 208y = 13312 \\ y = 64$
