Answer 3

To simplify the expression, let's first simplify the terms individually and then perform the subtraction.

Starting with -9 целых 3/7: -9 целых is the same as -9, so we have -9 + 3/7.

Next, let's simplify -(-6 целых + 4/7): -6 целых + 4/7 is the same as -6 + 4/7.

Now, let's substitute the simplified values back into the original expression:

-9 + 3/7 - (-6 + 4/7).

To remove the negative sign before the parentheses, we need to distribute the negative sign to each term inside the parentheses:

-9 + 3/7 + 6 - 4/7.

Combining like terms:

(-9 + 6) + (3/7 - 4/7).

-9 + 6 equals -3, and 3/7 - 4/7 equals -1/7.

Substituting the values back in:

-3 + (-1/7).

To add these two terms, we need to find a common denominator, which in this case is 7:

(-3 * 7)/7 + (-1/7).

Simplifying:

-21/7 - 1/7 = -22/7.

Therefore, -9 целых 3/7 - (-6 целых + 4/7) simplifies to -22/7.
