Question

Q.No. 1. Do as directed;
(1) which is not the solution of X - Y = 0
(Tick correct one)
(a) (1,1)
(b) (-1, 1)
(c) (1,-1)
(d) (1,0)​

Answer 1

Answer:

The answer will be (-1,1)

Step-by-step explanation:

as 1 option will is correct

by substituting values the answer will be 0 and same is applied on option 3 and 4

Answer 2

Answer:

"-2" can not be the solution of equation

Step-by-step explanation:

The question is in-complete, there must be another equation as well

Complete question would be

x-y=0

x-y-2=0

What can not be solution of this system of equation

Solution

x-y=0

x=y

Now, substituting, value of x in equation two

x-x-2=0

0-2=0

-2=0

Thus, we see that "=2" can not be the solution of equations
