It's difficult to tell what you're asking. It looks to me like:
-17x = -204 ---> x = (-204)/(-17) = 12
21 = -7n ---> n = 21/(-7) = -3
-143 = -11x ---> x = (-143)/(-11) = 13
-16 + x = -15 --> x = -15 + 16 = 1
n-8 = -10 --> n = -10 + 8 = -2
Is this what you mean?
Remember that when you multiply (or divide) two Negatives, you get a Positive.
A Negative * Positive = Negative; Negative / Positive = Negative;
Positive / Negative = Negative.
To isolate n in something like [n-8], you need to add 8 to both sides of the equation.
For the equation -17x = -204, divide both sides by -17 to get x = 12. For the equation 21 = -7n, divide both sides by -7 to get n = -3. For the equation -143 = -11x, divide both sides by -11 to get x = 13. For the equation -16 + x = -15, add 16 to both sides to get x = 1. For the equation n - 8 = -10, add 8 to both sides to get n = -2.

I'm not sure this was notated correctly. As written, this is -11x plus or minus 18, which doesn't factor.
