Question

x/a+y/b=0,(a+b)x+(a-b)y=a²+b² multiply by four...​

Answer 1

Step-by-step explanation:

A landmass surrounded by water on three sides or a three location is called peninsula

Answer 2

Step-by-step explanation:

x/a+y/b=0

=>bx+ay=0

=>x=-ay/b----

(a+b)x+(a-b)y=a²+ b²

-(1)

=>(a+b)x=a²+ b²+by-ay

=>x=(a²+b²+by-ay)/(a+b) =>-ay/b=(a²+b²+by-ay)/(a+b)

=>(a+b)(-a/b)y=a²+b²+y(b-a) =>y{(-a²-ab)/b -b +a}=a²+b²

=>y=(a²+b²)/{(-a²-b²)/b} =>x=a

=>y=-b

so, from Equation 1, x=-ax-b/b

Solution, (x,y)=(a,-b)
