ax-by= a²- b²​

Answer 1

Answer:

i dont know ² =i dont knw²

Answer 2

Answer:

hope it helps u all the best

Step-by-step explanation:

x/a + y/b = 2

⇒ ay + xb = 2ab----------( 1 )

ax - by = a² - b²---------( 2 )

from-----( 1 ) &-------( 2 )

multiply ( 1 ) by "a" ( 2 ) by "b"

abx + a²y = 2a²b

abx - b²y = ba² - b³

-------------------------------------------------

y(a² + b²) = 2a²b - ba² + b³

⇒ y(a² + b²) = a²b + b³

⇒ y(a² + b²) = b(a² + b²)

⇒ y = b [ put in -----( 1 )]

we get

⇒ ay + xb = 2ab

⇒ a(b) + xb = 2ab

⇒ xb = 2ab - ab

⇒ x = ab/b

⇒ x = a
