Answer 2

Answer:

x-y=2

Step-by-step explanation:

Given:

13x+7y=27(1)

7x+13y=15(2)

In first equation 13+7 gives 20 but According to equation(ATE) it is 27

So, 7 is left (27-20)

In second equation 7+13 also gives 20 but ATE it is 15

So , 5 is left in this one(20-15)

So, According to me x - y = (7-5) =2 ( Not sure)
