For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. The equation |x + 333.22 | = 12.78 can be used to find x, which represents the maximum and minimum temperatures at which nitrogen is a liquid.

is the maximum temperature at which nitrogen is a liquid.

is the minimum temperature at which nitrogen is a liquid.
