Question

Two​ trains, Train A and Train​ B, weigh a total of 437 tons. Train A is heavier than Train B. The difference of their weights is 415 tons. What is the weight of each​ train?

Answer 1

Explanation:

A + B = 437

A - B = 415 (for that sequence it is important to know that A is larger than B).

A = 415 + B

that we use now in the first equation :

415 + B + B = 437

2B = 22

B = 11

A = 415 + B = 415 + 11 = 426 tons

B = 11 tons
