You can proportionally divide this between the two supports, as we know that the closer support will take more of the load. The proportion would simply be 3/4 to the pin and 1/4 to the roller as we know the distances. Dividing 7.1kN into these proportions means the rollers vertical reaction is 1.76kN downwards and the pin is 5.33kN downwards.
