I can't parse the equation you posted. Could you retype it more clearly? A few tips:

- Use standard operators: +, -, *, /, and parentheses.
- Put the equals sign = between left and right sides.
- If helpful, write it in one line, e.g. "Solve: -x - 7 = -21" or use LaTeX like "Solve: -x - 7 = -21".

If you meant one of these common possibilities, here are quick solutions:

- If the equation is -x - 7 = -21, then -x = -14 so x = 14.
- If the equation is -x - (-x) = -x, then 0 = -x so x = 0.
- If the equation is (-x) / x = -1 (for x ≠ 0), then -1 = -1 (true for any nonzero x), so any x ≠ 0 works.

Please repost the exact equation (or a photo) and I'll solve it step by step.
