8. Реши уравнения. x-12 = 0 25 + x = 25 x: 108 = 1 y: 1 = 37 x⋅15=0 x⋅18 = 18

Решаем уравнения:

1. \[x - 12 = 0\] \(x = 12\)
2. \[25 + x = 25\] \(x = 0\)
3. \[x : 108 = 1\] \(x = 108\)
4. \[y : 1 = 37\] \(y = 37\)
5. \[x \cdot 15 = 0\] \(x = 0\)
6. \[x \cdot 18 = 18\] \(x = 1\)

Ответ: x = 12, x = 0, x = 108, y = 37, x = 0, x = 1
