Question

Trains Two trains, Train A and Train B, weigh a total of 278 tons. Train A is heavier than Train B

The difference of their weights is 200 tons. What is the weight of each train?
Train A weighs
tons.

Answer 1

From the description

a+b = 206

a-b = 26

Add the two equations to eliminate b

2a = 232

a = 116

b = 206 - a = 206 - 116 = 90

Train A weighs 116 tons and train B weighs 90 tons
