Answer by askmemath(368) (Show Source): You can put this solution on YOUR website!
2y + 4x = 8
y + 2x = 1
Multiplying with 2
2y+4x = 2
You will notice that is very similar to except that in the first equation the sum adds up to 8
and in the third equation the sum adds up to 2
How is that possible??
It isnt!!
So the system is Inconsistent!!
Alternatively, subtract from
2y + 4x = 8
2y + 4x = 4
0 = 4 which is not possible. So you can say the system in Inconsistent.
