Having trouble answering this chemistry question its just conversions?

A 26.20-g sample of a solid is placed in a flask. Toluene, in which the solid is insoluble, is added to the flask so that the total volume of solid and liquid together is 50.0 mL. The solid and toluene together weigh 47.54 g. The density of toluene at the temperature of the experiment is 0.864 g/mL. What is the density of the solid?
