Question

. The pair of linear equations x=y and x+y =0 has


​

Answer 1

Answer:

x=y and x+y=0 has unique solution.

Step-by-step explanation:

since we have

x=y

=> x-y=0 -----------------(i)

x+y=0 ------------------(ii)

Now comparing with standard equation we get,

a1x - b1y + c1 = 0 and,

a2x + b2y + c1 = 0

a1 = 1 , b1 = - 1 , c1 = 1

a2 =v1 , b2 = 1 , c2= 1

Now,

a1/a2 = 1/1 =1

b1/b2 = -1/1 = -1

since

a1/a2 ≠ b1/b2

therefore x=y and x+y=0 has unique solution
