You can put this solution on YOUR website! y = -3x + 1 and 3x + y = -1
----
Substitute for "y" and solve for "x":
3x + y = -1
3x +(-3x+1) = -1
1 = -1
---
That is a contradiction.
Why did it happen?
You assumed the x and the y in the 2 equations
had the same value. They don't.
There is no (x,y) that fits both equations.
--
That system of two equations has no solution.
If you graphed the two equations you would
find that they are parallel: no common point.

You can put this solution on YOUR website! To solve the system by substitution plug y=-3x+1 in the equation 3x+y=-1
3x-3x+1=-1 =>0*x=-2 From the last equation we conclude that the system is inconsistent.
