Question

the pair of linear equations X equal to Y and X + Y equal to zero has​

Answer 1

Answer:

Step-by-step explanation:

the equation becomes

x+y=0

x-y=0

therefore it has unique solution

x=0

y=0

Answer 2

The pair of line has intersecting lines and has exactly one unique solution

Step-by-step explanation:

given equations :

x=y

x-y=0..(1)

x+y =0 ..(2)

here

$a_1 = 1\\a_2=1\\b_1=-1\\b_2=1$

then

$\frac{a_1}{a_2} = \frac{1}{1}\\\frac{b_1}{b_2} =\frac{-1}{1} \\\frac{a_1}{a_2} \neq \frac{b_1}{b_2} \\1 \neq -1$

hence  , The pair of line has intersecting lines and has exactly one unique solution
