Answer 1

$\huge\boxed{\fcolorbox{cyan}{grey}{Solution:-}}$.

➡Given here.

♠X+y = 6..........(1).

♠X-Y = 4...........(2).

➡Find here.

♠x²+y²=?.

♠x²-y²=?.

➡Now,subtract equations (1)-(2).

=> 2y= 2.

=>y = 1.

➡By ,(1).

=> x+1=6.

=>x = 5.

➡Thus:-

♠Value of x=5.

♠Value of y=1.

➡Now,

♠X²+y²= 5²+1²=25+1=26.

♠x²-y²=5²-1²=25-1=24.

➡Hopes its helps u.
