Let C,H,L be the weights (in lbs) of the cow, horse, and lion respectively.
"the cow weighs 600lbs more than the lion" translates to the equation:
C = L+600
"horse weighs 129 less than the cow" (I'm assuming 129 is 129lbs) becomes:
H = C-129
Substituting the first equation into the second tells us that:
H = (L+600)-129 = L+471
Rearranging gives:
L = H-471
So the lion weighs 471 lbs less than the horse.
Hope this helped,
