I used the comparison method because I dont know what type of method you needed, sorry. The methods I know would be: the Comparison Method (what I used), the Substitution Method, Elimination Method,Inverse Matrix Method, Cramer's Rule, and the Gauss-Jordan Method.
You can also rewrite this equation to 3x-y=-7 and x-y=-1.
I'm sorry, I dont know what kind of answer you're looking for. I really hope this helps.

Answer:
Probability of each situation is 1/3 .
Step-by-step explanation:
There are 3 possibilities
1- Train will arrive early
2- Train will arrive on time
3- Train will arrive late
Formula for Probability of event a is = n(a)/Sum of events
In this case sum of events = 3
So
Probability of early arrival = 1/3
Probability of on time arrival = 1/3
Probability of late arrival = 1/3
