Question

I think you solve this correctly​

Answer 1

Answer:

x=7 and y=1

Step-by-step explanation:

Number of subsets of A= 2×n(A)=2×4=8

Then,x+y=8

Thus y=(8-x)

Number of subsets of B= 2×n(B)=2×3=6

Therefore, x-y=6

=›x-(8-x)=6

=›x-8+x=6

=› 2x-8=6

=› 2x=6+8

=› 2x=14

=› x=14÷2

=› x=7

Thus, x=7 and y=(8-x)=(8-7)=1
