1000 - x = 35 + 6 × 8.81 ÷ y = 63 ÷ 7
1000 - x = 35 + 6 × 8.81 ÷ y
1000 - x = 35 + 52.86 ÷ y
x = 1000 - 35 - 52.86 ÷ y
x = 965 - 52.86 ÷ y
x × 8 = 100 - (4 × 9)
8x = 100 - 36
8x = 64
x = 64 / 8
x = 8
Подставляем x = 8 в первое уравнение:
1000 - 8 = 35 + 6 × 8.81 ÷ y
992 = 35 + 52.86 ÷ y
992 - 35 = 52.86 ÷ y
957 = 52.86 ÷ y
y = 52.86 / 957
y ≈ 0.055
Ответ: x = 8, y ≈ 0.055
