2х+18 разделить на х-3 равно 12
найти корень уравнения
1
ответ
To divide 2x+18 by x-3, we can use long division method:
```
2
___________
x - 3 | 2x + 18
2x - 6
-------
24
```
Therefore, (2x+18)/(x-3) = 2 + 24/(x-3)
To find the root of the equation 2 + 24/(x-3) = 12, we can first subtract 2 from both sides:
24/(x-3) = 10
Then multiply both sides by (x-3):
24 = 10(x-3)
Simplifying:
24 = 10x - 30
54 = 10x
x = 5.4
Therefore, the root of the equation is x = 5.4.
