so if temp increases equilibrium will shift to the direction that has an endothermic reaction.
if concentration of a substance increases equilibrium will shift to reduce this concentration.
if pressure increases the equilibrium will shift to the side of the equation which has the least amount of moles

So, say you have a reversible reaction A + B = C + D and the forward reaction is exothermic (and thus the reverse being endothermic).
if you increase the temperature of the reaction you will create more A + B (as the reverse is endothermic) and so the reaction moves to achieve equilibrium byreleasing more energy in the forward reaction to reduce the temperature (and this reducing your change). Therefore, the position of equilibrium has shifted left by creating a change on the right.
