Two​ trains, Train A and Train​ B, weigh a total of 379 tons. Train A is heavier than Train B. The difference of their weights is 255 tons. What is the weight of each​ train?

A = 317

B = 61

Step-by-step explanation:

The following equation can be gotten from the question given. This will be:

A + B = 379 i

A - B = 255 ii

From equation i, make A the subject of the formula

A = 379 - B iii

Put the value of A in iii into equation ii

A - B = 255

(379 - B) - B = 255

379 - B - B = 255

379 - 2B = 255

2B = 379-255

2B = 124

B = 124/2

B = 62 tons

Since A + B = 379

A + 62 = 379

A = 379 - 62

A = 317 tons
