Question

if x-y=2 find value of of y with explanation

Answer 1

x -y = 2
-y = 2-x
y = -2 + x

Putting value of x as 0
y = -2+0
=0

Putting value of x as 1
y = -2+1
=-1

Putting value if x as 2
y = -2+2
=0

So there can be many values of y by putting different values of x

Answer 2

X = 2+Y
X-2 = Y
Y = X-2.

Answer will be this.


But probably your question is wrong it is not correct.
