Answer 1

Answer:

bio

Step-by-step explanation:

x²-y²/xymust be subtracted from 1/2(x+y)to get 5x-y

Answer 2

1/2(y-9x)

let's asse the variable z which is to b subtracted from 1/2(x+y) to get 5x-y

1/2(x+y) - z=5x-y

x-y-2z=10x-2y

-2z=9x-y

z= -(1/2(9x-y))

there fore z=1/2(y-9x)

hope this helps u

thank you
