Answer 2

To help you with this equation, I need some clarification as the provided expression appears to be unclear and contains potential errors. There seem to be some typos or formatting issues. Here's how I interpret the equation:

1. "3(х – 0,3) = 3 1 х + 7"
2. "только 31 это дробь"

Let's address the first equation:

3(х – 0,3) = 3 * (х - 0.3) = 3 * х + 7

It seems that there might be a typo or confusion in the equation. The right-hand side of the equation "3 * х + 7" does not seem to be consistent with the left-hand side "3(х – 0,3)."

If you meant to write the equation like this:

3(х – 0.3) = 31

Then we can solve it as follows:

Step 1: Distribute the 3 on the left-hand side: 3 * х - 3 * 0.3 = 31 3 * х - 0.9 = 31

Step 2: Isolate х by moving -0.9 to the other side of the equation: 3 * х = 31 + 0.9 3 * х = 31.9

Step 3: Divide both sides by 3 to solve for х: х = 31.9 / 3 х ≈ 10.6333

Now, let's address the second statement "только 31 это дробь." It translates to "only 31 is a fraction."

It seems like there might be a translation issue here because 31 is not a fraction; it is an integer.
