Most probably, yes.
Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.
If your question was about a solution to x + y = 1 the point (0,1) IS an answer.
x=x+1 0=1 this is impossible so there is no solution.
Yes, but so is everything else.
-3 + 4.5 + 8 + 6 = -x-1 15.5 = -x-1 x-1 = -15.5 x = -1/15.5 x = -2/31
solution: y = 0 x = -1
The solution is (x, y, z) = (2.5, 1, 2.5).
first we assume this to be true. x+1=x+2 x=x+1 x-x=1 0=1 this is not true, so the initial premise that this problem has a solution must be false. There is no solution.
If you mean x+5y = 4 then (9, -1) is the solution
In the equations Y=X-1 and Y=-X+1, the solution is (1,0)
x+1=x+2 x=1+2+x 0x=1+2 0x=3 0x=/=3 (=/= means does not equal) so there is no solution
The solution is: x = 1 and y = -1
x=x+1 0=1 this is impossible so there is no solution.

Yes, but so is everything else.
y = x + 1
-3 + 4.5 + 8 + 6 = -x-1 15.5 = -x-1 x-1 = -15.5 x = -1/15.5 x = -2/31
solution: y = 0 x = -1
There is no solution or simplification possible.
