Question 45160: Solve each of the following systems by addition.If a unique solution does not exist ,state whether the system is inconsistent or dependent.


x + 5y =10
-2x -10y =-20

If you multiply both sides of the first equation by -2, you will find that the first equation is exactly the same as the second equation. In this case, the system is said to be dependent and there is NOT a unique solution. The solution is actually the entire line.
