Question

Which system of linear equation has no solution?

x+y=9
x-y=3

-5x=9-y
-5x+y=3

2x+y=4
x-3y=9

4x+3y=5
3x-2y=14

Answer 1

Answer:

-5x=9-y

-5x+y=3

Step-by-step explanation:

adding the y at the top equation to the left makes the equation -5x+y=9. When you go to subtract the bottom from top you lose all variables.
