It would help if the expression was given!
Depends what the expression is. Just plug in 8 for y in the expression and that'll do it for you.
The = sign
You don't, unless you know either the value of x or what the expression equals.
The answer is -369.

Yes.
The = sign
The = sign
you test it by giving the letters a value say if X equals 5 and Y equals 7 then you calculate both expressions with that value. If both answers are the same, then the simplified expression is correct, or an equivalent.
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
You don't, unless you know either the value of x or what the expression equals.

The answer is -369.
