In what situation does -q=w?

From my understanding if I'm correct.... Delta u is 0 in an isolated system in which there is no temperature change. That means the system is isothermal, the temperature is constant and delta u is equal to 0. Therefore q=-w or vice versa -q=w. Hope thats makes sense and is helpful.
