If events A and B are independent, what must be true?
A. P(A|B) = P(B)
B. P(A|B) = P(A)
C. P(A) = P(B)
D. P(A|B) = P(B|A)

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
