Log On
x + 5y =10
-2x -10y =-20
: Solve each of the following systems by addition.If a unique solution does not exist ,state whether the system is inconsistent or dependent. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! If you multiply the top equation by minus two, you go from
x + 5y =10
-2x -10y =-20
to
-2x -10y =-20
-2x -10y =-20
You can see that these are the very same line.
Thus the system is dependent and there ar an infinite number of solutions.
