Solving the Equation

To solve the equation 27-х/21=9/21, we can follow these steps:

1. Isolate the Variable: First, we isolate the variable x by getting rid of the fraction on the left-hand side of the equation. 2. Simplify: Then, we simplify the equation to solve for x.

Step-by-Step Solution

1. Isolate the Variable: - Multiply both sides of the equation by 21 to get rid of the fraction: ``` 21 * (27 - x/21) = 21 * 9/21 ```

2. Simplify: - Simplify the equation: ``` 21 * 27 - x = 9 ```

3. Solve for x: - Subtract 21 * 27 from both sides of the equation: ``` -x = 9 - 21 * 27 ```

- Finally, solve for x: ``` x = 21 * 27 - 9 ```

So, x = 567 - 9 = 558.

Therefore, the solution to the equation 27-х/21=9/21 is x = 558.
