I know the matrices S1 and S2 commute, is also know that S1,z + S2,z = S,z couldn't that help?

Homework Statement Find the energy levels of a 2-spin 1/2 system with spinoperators S1 and S2 in an external magnetic field. The hamiltonian is of the form, H= A ( 1-\frac{2S_{1}}{h} . \frac{2 S_{2}}{h} )+ \frac{\mu B}{h}(S_{1,z}+S_{2,z}) The h is a h-bar, constants A, B, and S1 and S2 the...
