Um idk the answer but I’m sure your friends or teachers can help you?
Answer:
2
Step-by-step explanation:
The answer would be 2 because it reduces to the same system of equations as the original, which I knew since the first equation was the same and if you divide everything in the second by 2, you'll get 3x-y=8. :)
unfortunately I cant manage to understand ur question
5.7 is your answer
Hope this helps.
