12 - х = 6

x = 12 - 6

x = 6

12 - 6 = 6

6 = 6

Answer 2

Let's break down the equation step by step to check its validity:

1. The original equation is: 12 - x = 6x.
2. Then, you added x to both sides of the equation: 12 = 6x + x.
3. Next, you simplified the right side: 12 = 7x.
4. Now, you divided both sides by 7 to isolate x: x = 12/7.
5. Finally, you checked the result by substituting x back into the original equation: 12 - (12/7) = 6 * (12/7).

Now, let's verify the last step: 12 - (12/7) = 84/7 - 12/7 = 72/7. 6 * (12/7) = 72/7.

The result is consistent: 12 - (12/7) = 6 * (12/7) = 72/7.

So, your calculations are correct! The value of x is indeed 12/7 or approximately 1.7142857.
