Question

mx-ny = m²+n²
x+y = 2m

From : Simultaneous Linear equations ​

Answer 1

Answer:

mx−ny=m^2+n^2

mx+my=2m^2

- - -

−my−ny=m^2+n^2−2m^2

⇒(x+y=2m)×m

−y= m+n(n 2 −m 2 )

(n^2-m^2 )

⇒y= ⇒y=(m^2-n^2) =

(m+n)

(m+n) (m−n)

(m+n)

y=m−n

Substitute 'y' in equaltion x+y=2m

x=2m−m+n

x=m+n

(x,y)=[m+n,m−n]
