42 times 2 because 84 divided by 24 equals 2. Also, 84 divided by 2 equals 24.
Answer: A proper subset is one that contains few elements of the original set whereas an improper subset, contains every element of the original set along with the null set.
We have that
x - 3y = 12 and -x + y = 4
We add the 2 equations together
x - 3y + (-x + y) = 16
-> -2y = 16
-> y = -8 (1)
We plug y = -8 into -x + y =4
-> -x - 8 = 4
-> -x = 12
-> x = - 12 (2)
From (1) and (2) we could conclude that the answer is B
