I have this problem with torque and not sure if I approached it correctly or not.(adsbygoogle = window.adsbygoogle || []).push({});

A door is 1m wide and 2m high, has a mass of 20kg, and is supported by two hinges, each bearing 1/2 the weight of the door. The hinges are attached to the left of the door at locations 1/2m above the bottom edge and 1/2m below the top edge. It is in static equilbrium.

So, I write out the two conditions:

vector sum of net force= (Wdoor along -j)+(Fsupport1 along j)+(Fsupport2along j)=0

vector sum of net torque= 0

I'm stuck at this, I don't know if I wrote the equation right or not. Please help. I don't know where to put the pivot point in this example either. Is the direction for the forces right? Please help.
