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!

3. so my equation would be:

50x+125=4725
