is (0, 1) a solution to x + y = 1.
Yes.
Substitute the values for x and y and see what you get:
x + y = 0 + 1 = 1 as required, so yes.
x=x+1 0=1 this is impossible so there is no solution.
Yes, but so is everything else.
solution: y = 0 x = -1
-3 + 4.5 + 8 + 6 = -x-1 15.5 = -x-1 x-1 = -15.5 x = -1/15.5 x = -2/31
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
solution: y = 0 x = -1
-3 + 4.5 + 8 + 6 = -x-1 15.5 = -x-1 x-1 = -15.5 x = -1/15.5 x = -2/31
There is no solution or simplification possible.
