Question

реши уравнения 80000÷y=4000-2000
12000×x=24000
12000×x=800×30
(500000-100000)÷b=80

Answer 1

80000÷y=4000-2000
80000÷y=2000
y=80000÷2000
y=4000
------------
80000÷4000=4000-2000
2000=2000

Answer 2

80000 ÷ у = 2000
у= 80000 ÷ 2000
у= 40

12000 × х = 24000
х = 24000 ÷ 12000
х = 2

12000 × х = 24000
х = 24000 ÷ 12000
х = 2

400000 ÷ b = 80
b = 400000 ÷ 80
b = 5000
