Equation: -1.1 - (c / 0.1) = 20.9.
c / 0.1 = 10c, so -1.1 - 10c = 20.9.
Add 1.1 to both sides: -10c = 22.0.
Divide by -10: c = -2.2.
Check: -1.1 - (-2.2 / 0.1) = -1.1 - (-22) = -1.1 + 22 = 20.9. Correct.
c / 0.1 = 10c, so -1.1 - 10c = 20.9.
Add 1.1 to both sides: -10c = 22.0.

Check: -1.1 - (-2.2 / 0.1) = -1.1 - (-22) = -1.1 + 22 = 20.9. Correct.
