Answer:
No Solution
Step-by-step explanation:
You can use the expression for y provided by the first equation to substitute for y in the second equation.
y = x +1
x -(x +1) = 1
-1 = 1
There are no values of the variables x and y that will make this equation true. The system has No Solution.

Additional comment
Solving the second equation for y gives ...
y = x -1
This graphs as a line parallel to the line representing the first equation. A system describing parallel lines has no solution, because the lines never meet, and the solution is the point where they meet.
Answer:
no possible answer.
Step-by-step explanation:
1. y = x+1
2. x-y = 1
3. x = 1+y
Substitute equation 3 into the x in equation 1:
y = (1+y)+1
y = 2+y
y-y = 2
0=2
"0 = 2" isn't valid, thus there is no possible answer to this question.
