1) x - 75 = 125x = 125 + 75x = 200
Проверка: 200 - 75 = 125
2) x : 10 = 250x = 250 * 10x = 2500
Проверка: 2500 : 10 = 250
3) 140 : x = 7x = 140 / 7x = 20
Проверка: 140 : 20 = 7
4) 32 * x = 32x = 32 / 32x = 1
Проверка: 32 * 1 = 32
1) x - 75 = 125
x = 125 + 75
x = 200
Проверка: 200 - 75 = 125
2) x : 10 = 250
x = 250 * 10
x = 2500
Проверка: 2500 : 10 = 250
3) 140 : x = 7
x = 140 / 7
x = 20
Проверка: 140 : 20 = 7
4) 32 * x = 32
x = 32 / 32
x = 1
Проверка: 32 * 1 = 32
