slamgirl [31]

Answer:

A: 114, B: 84

Step-by-step explanation:

Let A be weight of Train A, B be weight of Train B. Since A is heavier than B by 30 tons, A = B + 30. Since A + B = 198, you can substitute for A to get (B+30) + B = 198. Then simplify so 2B = 168 and B = 84.

Then plug B into A = B+30 to get A = 114.
