Question

3) -1 is not a solution of the
equation
a) x+1=0
b) 2y +3 =1
c) X - 1 = 2​

Answer 1

Answer:

I think the answer is

2y + 3= 1

Not sure

Answer 2

Answer:

Option (c)

Step-by-step explanation:

Put x=(-1)  or y=(-1) in each of the equations. If LHS and RHS is equal, it satisfies.

If we see, in the 3rd equation, x-1=2

-1-1=2

-2=2----------> It is not a solution
