Question

solve for x and y : mx-ny=m2+n2 and x+y=2m

Answer 1

Answer:

mx-ny=(m^2+n^2).....….......…………......(1)

1x+1y=2m...............................(2)

x/(-2mn-m^2-n^2)=y/(m^2+n^2-2m^2)

=-1/(m+n)

x/-(m+n)^2=y/(n^2-m^2)=-1/(m+2)

x=(m+n)^2/(m+n=(m+n)

Step-by-step explanation:

y=-(n-m)=(n+m)/(m+n)=(n-m)=(m-b). thus ,x=(m+n) , y=(m-n) answer.
