Two​ trains, Train A and Train​ B, weigh a total of 530 tons. Train A is heavier than Train B. The difference of their weights is 352 tons. What is the weight of each​ train?

A+B=530

 

A-352=B

Add 352 to both sides

A=B+352

 

Substitute

(B+352)+B=530

2B+352=530

2B=178

B=89

 

So if A=B+352 then

A = 89+352

A = 441

 

Train A = 441 tons

Train B = 89 tons
