Same energy electron/phtoton x-rays (vcaa Q10 2010) Light matter

Hey guys,
Anyone have some easy steps to follow to approach these type of questions?
eg:
If same wavelength, they have same momentum, so use the momentum formula = p=mv or something?
I did:
1) wavelength(electron) = h/squareroot(2*KE*m)
2) Energy(photon) = hc/wavelength(electron)
