SolveforX and YX- Y= a - b aX- bY = a^2 + b^2 ​

Answer»

Answer:

x- y= a - B

x=a-b+y

PUT value in second equation. ax- by = a² + b²

a(a-b+y)- by= a² + b²

a²-ab+AY-by=a²+b²

a(a-b)+y(a-b)=a²+b²

(a+y)(a-b)=a²+b²

a+y=(a²+b²)/(a-b)

y=(a²+b²)/(a-b) -a

y=(a²+b²-a²+ab)/(a-b)

y=(b²+ab)/(a-b)

put in first equation

x=a-b+y

x=a-b+(b²+ab)/(a-b)

x=(a²-ab-ba+b²+b²+ab)/(a-b)

x=(a²+b²-ab)/(a-b)

hope it will help you kindly MARK the answer as BRAINLIST
