Answer: Train A weighs 427 tons and Train B weighs 67 tons
Step-by-step explanation:
We know that Train A + Train B = 494 tons
We also know that Train A - Train B = 360 tons.
We can set up a system with these two equations.
A + B = 494
+ A - B = 360
2A = 854
Train A = 427 tons
Plug this into the first equation.
427 + B = 494 Tons
Train B = 67 Tons.
You can check this by plugging in both values into the second equation.
427 - 67 = 360
360 = 360.
Hope this helps!
