Answer:

Train A weighs 252 tons and Train B weighs 13 tons

Step-by-step explanation:

Let "A" represent the weight of Train A and "B" represent the weight of train B.

We can use this to set up a system of equations:

A+B=265

A-B=239

We can solve using elimination. Let's subtract the second equation from the first to cancel out A.

2B=26

Divide both sides by 2

B=13

Plug 63 back in for B in any of the two equations:

A+13=265

Subtract 13 from both sides

A=252

Train A weighs 252 tons and Train B weighs 13 tons
