+19 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?
+37146 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
+129847 -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
+37146 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
