    Let x = the weight of each car (they all weigh the same)

    Let 50x = the weight of all 50 of them

    125 = the weight of the locomotive

    4725 = the weight of everything (cars and locomotive)

    50x+125=4725

    Can you solve this equation to find the weight of one car? Just subtract 125 from both sides, then divide both sides by 50.

    Good luck!
