Use the elimintation method?

-x=-1+y

x+y=4

___ ____

y=y+3

This is never true so the system has no solution.

What do I do?

y = -x -1 and y = -x - 4 m = slope = -1 for both of them

these equations are parallel lines (they do not intersect) ....they have the same slope = -1

so there is no solution

-x=-1+y subtract y from both sides -x - y = -1

x+y=4

Add these equations and we have that

0 = 3 .......since this is never true, this system has no solutions
