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

 

 

cool cool cool
