b. 1,-1
c. -1,1
d. 1,0​

Answer 1

Answer:

I think option d.....

hope it is correct

Answer 2

Answer:

(b.), (c.) and (d.) are not the solutions of X - Y = 0.

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

Step-by-step explanation:

Just put the values given in the options one-by-one. The options that don't fit are not solutions of X - Y = 0.

a. 1, 1

X - Y = 1 - 1 = 0

We got 0. Therefore, this is a solution.

b. 1. -1

X - Y = 1 - (-1) = 1 + 1 = 2

We didn't get 0. Hence, this is not a solution.

c. -1, 1

X - Y = -1 - 1 = -2

We didn't get 0. Hence, this is not a solution.

d. 1, 0

X - Y = 1 - 0 = 1

Again, we didn't get 0. So, this is also not a solution.
