Re: New LC
It appears that the system of equations may have been tweaked. Looking at the first two equations, we have:

u + 2o = 135

Since no equation other than the second one in each system has a strictly numerical term (that is, a term containing no variable), this new system cannot be simply a "rearrangement" of the original one, since (I'm pretty sure) no combination of the original equations would have created that new second equation.
However, before anybody panics, plug the original solution values for each letter into the new system's equations. As long as all the new equations work out to be true statements, the original solution of "599" is still valid.
For instance, the new third equation, "5d + 2c = 6m", evaluates as 5(6) + 2(30) = 30 + 60 = 90 for the left-hand side and as 6(15) = 90 for the right-hand side, so the original system's variable values work in the new third equation. Test all the other new equations, to verify the original solution.
