General physics (torque)

A 200-N scaffold is held up by a wire at each end. The scaffold is 18m long. A 650-N box sits 3.0m from the left end. What is the temsion in each wire?

I have worked this problem several times but none of my answers are close to the choices I have on my paper. I tried it like this FT= -200(9) + 650(3) this is for the right side and FT=200(9)+ 15(650) for the left but it is not correct.

The choices for the answers are A)left wire=640N;right wire+210N B)left wire+195N; right wire=975N C) Left wire=295N;right wire=1000N D)left wire=520N; right wore=130N.

Mine do not come close to any of the answers. What have I done wrong. I greatly appreciate your help on this problem. Thank you
