Answer 2

Вот так))))))))))))))))))))

Answer 3

Sure, let's solve for x:

5.3 + 6.9 + x + 0.4 = ?

We can start by combining the constant terms (the numbers that don't include x):

5.3 + 6.9 + 0.4 = 12.6

Now we can simplify the equation:

12.6 + x = ?

To solve for x, we can subtract 12.6 from both sides of the equation:

12.6 + x - 12.6 = 0 + x

Simplifying the left side gives:

x = -12.6 + x

So the value of x is just -12.6.

Therefore, the final answer is: x = -12.6.
