The system
2x - y = 5
-4x + 2y = -18
has no solutions.
These lines are parallel.
The system is called inconsistent.
Answer by rajagopalan(174) (Show Source): You can put this solution on YOUR website!
2x - y = 5
-4x + 2y = -18
LHS is the same -4x+2y =-2(2x-y)
So both LHS are same. This can not construe a system of equations.
If you consider each eqn individually u can have infinite solutions.
Good luck
