Answer:
train a weighs 177 and train b weighs 90
Step-by-step explanation:
train a weighs 87 more tons than train b but both combined is 267.
a + b = 267
267 - 87 = 180
divide by two to get the weight of train b
180/2 = 90
add the 87 to find the weight of train a
90 + 87 = 177
check
90 + 90 + 87 = 267
