S,T: V onto W are both linear maps. Show that M:={x out of V s.t. Sx out of Range(T)} is a subspace of V(adsbygoogle = window.adsbygoogle || []).push({});

I know that to show M is a subspace of V I must show:

i. 0 out of M

ii. For every u, v out of M, u+v out M

iii. For every u out of M, a out of F, au out of M.

I just don't know how to start it, can someone help?
