Найти корни уравнений 0,30 x+ 0,47 = 12,8 Помогите сделать решение

Answer 1

0.30х+0.47=12.8
0.30х=12.8-0.47
0.30х=8.1
х=8.1 : 0.30=27
х=27

Answer 2

0,30х=12,8-0,47
0,3х=12,33
х=12,33:0,3
х=41,1

Answer 3

Solving the Equation 0.30x + 0.47 = 12.8

To solve the equation 0.30x + 0.47 = 12.8, we can follow these steps:

1. Subtract 0.47 from both sides of the equation: This will isolate the term with x on one side of the equation.

2. Divide by 0.30: After subtracting 0.47 from both sides, we can divide by 0.30 to solve for x.

Step-by-Step Solution

1. Subtract 0.47 from both sides: ``` 0.30x + 0.47 - 0.47 = 12.8 - 0.47 0.30x = 12.8 - 0.47 0.30x = 12.33 ```

2. Divide by 0.30: ``` x = 12.33 / 0.30 x = 41.1 ```

So, the solution to the equation 0.30x + 0.47 = 12.8 is x = 41.1.

This solution was obtained by subtracting 0.47 from both sides of the equation and then dividing by 0.30.
