Question 103572: 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

You can put this solution on YOUR website!
By inspection, you can see that multiplying x+5y=10 by -2 you get the second equation. So, you actually have one equation with two unknowns. You cannot solve it.
