Step-by-step explanation:
Hi there!
So we know that the two train together is a total of 192 tons and the difference of their weights is 120 tons...
Ok let think...
When we’re looking at the once place, you’ll see a two... this means that the two train both have a ending of 1 since 2 is split into 1...
That would be another clue..
Now let think again...
If it would be 151 and we subtract by 120.. we would get...

Well it ends with a 1 so it would be perfect but we have to see if 151 and 31 together adds up with the total of 192..

This means that train A could be 151 tons or 31 tons and train B can also be wither 151 tons or 31 tons...
The slope is 2. y2-y1/x2-x1
6(10+z+3)
= (6)(10 + z +3)
= (6)(10) + (6)(x) + (6)(3)
= 60 + 6x + 18
= 6x + 78
