Задание 9
20 - (0.5y + 11.55) = 0.45 <=> 20 - 0.5y - 1.55 = 0.45 <=> 20 - 1.55 - 0.45 = 0.5y <=> 20 - 2 = 0.5y <=> 18 = 0.5y <=> y = 18 * 2 <=> y = 36
38.82 - (11.3 + 28x) = 21.92 <=> 38.82 - 11.3 - 28x = 21.92 <=> 38.82 - 11.3 - 21.92 = 28x <=> 27.52 - 21.92 = 28x <=> 5.6 = 28x <=> x = 5.6 / 28 <=> x = 56 / 280 <=> x = 5
Задание 10
Пусть x(кг) - вес абрикосов в 1 ящике. Тогда, 7 * 9.5 + 6 * 8.7 + 8x = 206 <=>
8x = 206 - 7 * 9.5 - 6 * 8.7 <=> 8x = 206 - 66.5 - 52.2 <=> 8x = 87.3 <=> x = 87.3 / 8 <=> x = 10.9 (кг)
Пусть x(кг) - вес ящика картофеля, тогда 17.2 * 7 + 3x = 161.8 <=> 3x = 161.8 - 120.4 <=> 3x = 41.4 <=> x = 41.4 / 3 <=> x = 414 / 30 <=> x = 13.8 (кг)
тк смежные всегда в сумме дают 180
