Question

Two​ trains, Train A and Train​ B, weight a total of 301 tons. Train A is heavier than Train B. The difference of their weights is 217 tons. What is the weight of each​ train?

Answer 1

Train A's weight is 259 tons

Train B's weight is 42 tons

Explanation:

Let x represent train A's weight, and y represent train B's weight.

Since they both weigh 301 tons

The equation is: x+y = 301

The difference in their weight is 210, and train A is heavier

So equation is: x - y = 217

x+ y =301

x- y = 217

2x = 518

x = 259 tons

Now find train B

301 - 259 = 42 tons

Answer 2

Train A = 259

Train B = 42
