How to simplify Simplifying and rearrangerearranging a setsystem of equations?

I have derived a set of equations of motion and now want to rearrange and simply them, but I am not sure which command I should use.

For example, I have: (1) dF_1 + eF_2 == Ma; (2) F_1 == m + n; (3) F_2 == f + g; (4) m == K + L;

d F_1 + e F_2 == M a; 
F_1 == m + n; 
F_2 == f + g; 
m == K + L;

Now I want to eliminate F_1F_1, F_2F_2, and mm, since they are redundant. I tried "Eliminate"Eliminate, but it gave me weird results when I had more than one set of such equations. What is the best command I should use to rearrange and simplify these equations? Thanks!!!
