Question

(I) which is not the solution of X-Y=0 (a) (1, 1) (b) (-1 , 1) (c) (1 , -1) (d) (1, 0)​

Answer 1

Answer:

hey mate here's your answer

Step-by-step explanation:

c.) ( 1 , -1 )

Answer 2

Answer:

I think so the question is wrong because (b), (c) and (d), are not the solutions of X-Y=0.

If the question would have been that which is the solution of X-Y = 0 then the answer would have been (a).

Step-by-step explanation:

Because,

b) X= (-1) c) X= 1 d) X= 1

Y= 1 Y = (-1 ) Y = 0

X-Y. = 0 X-Y = 0 X-Y. = 0

(-1) -1 = 0 1-(-1) = 0 1-0 = 0

-1 -1 = 0 1+1 = 0 1 ≠ 0

-2 ≠ 0 2 ≠ 0

Whereas,

a) X= 1

Y= 1

X-Y = 0

1-1 = 0

0 = 0

So, the answer for the question:

which is not the solution of X-Y=0 is (b), (c) and (d)

Whereas, the answer for the question:

which is the solution of X-Y = 0 is (a)
