Two trains, Train A and Train B, weigh a total of 368 tons. Train A is heavier than Train B. The difference of their weights is 340 tons. What is the weight of each train?

- Thanks in advance.

let's start by defining two variables: A and B, for trains A and B, respectively.

we can now create a system of equations:

A + B = 368 ("...weigh a total of 368 tons.")

A - B = 340 ("The difference of their weights is 340 tons.")

now, let's add up these two equations.

A + B + A - B = 368 + 340

2A = 708

A = 354

to solve for B, we just plug in our value of A into one of our initial equations.

354 + B = 368

B = 368 - 354

B = 14

hope this helped! please let me know if you have any questions :)
