To solve this equation, we need to first simplify both sides of the equation.

On the left side, we have -10целых - 3/7 - x.

On the right side, we have -9целых - 2/3.

To simplify the left side of the equation, we need to combine the целых terms and the fraction.

-10 целых - 3/7 can be written as -7 3/7, which is equivalent to -7 3/7.

So the left side of the equation simplifies to -7 3/7 - x.

Now we have:

-7 3/7 - x = -9 целых - 2/3

Next, we need to get the x term alone on one side of the equation.

To do this, we can add x to both sides of the equation:

-7 3/7 - x + x = -9 целых - 2/3 + x

This simplifies to:

-7 3/7 = -9 целых - 2/3 + x

Now, we need to add 9 целых and 2/3 to both sides in order to isolate x:

-7 3/7 + 9 целых + 2/3 = x

Next, we need to convert all the terms to a common denominator to add them together.

This simplifies to:

-51/7 + 81 + 2/3 = x

Now we need to compute the sum and simplify it:

-365/21 + 81 + 14/21 = x

-365/21 + 81 + 14/21 = x

-365/21 + 85 + 14/21 = x

Combined, this becomes:

-250/21 + 14/21 = x

-236/21 = x

Therefore, x = -236/21.
