Two trains, Train A and Train B weigh a total of 479 tons. Train A is heavier than Train B. The difference of their weights is
379 tons. What is the weight of each train?
1 answer:
Answer:
A= 429
B= 50
Explanation:
A+B= 479 (take away)
A-B= 379
A-A+B+B= 479-379 (simplify)
2B= 100
I think you know how to do it now..
B=50
A=50+379 ---> 429
This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!
