SOLUTION: Solve the following by addition. If a unique solution does not exist, state whether the system in inconsistent or dependent.
x + 5y = 10
-2x - 10y = -20
I appreciate any help

You can put this solution on YOUR website! multiplying the first equation by -2 results in the second equation
... this means that the equations are essentially the same
the system is consistent (it is the same equation)
... but because there is only one equation, there is no unique solution (dependent)
