Calculate ΔE, and determine whether the process is endothermic or exothermic for the following cases:(A) A system absorbs 105 kJ of heat from its surroundings while doing 29 Kj of work on the surrounding;(B) q = 1.50 kJ and w = -657j; (C) the system releases 57.5 kJ of heat while doing 22.5 kJ of work on the surrounding.

Im confused with the question, im pretty sure the equation is ΔE = q+pΔv

im not sure what to do can anyone help me, thanks.
