Dear Alpha

you have not given the wedge angle. assuming it to be theta

see the pic for the solution.

All the best.

The equations are..For mass m is mgsina-T=m(2f) and for mass 2m is mg-2T=2m.f where a is angle of inclination and f is accelaration.From constraint it can be proved that booth will have same acc.

at mass 2M

        2Mg-T=2Ma.............1

let the angle of incline be @

therefore at mass M

            T-Mgsin@=Ma..........2

adding 1 and 2

2Mg-Mgsin@=3Ma

 a=g(2-sin@)/3            

accleration of mass M and 2M will be samel ......
