Question 121932
If you try to solve by the elimination method, multiply the first equation by 2 and add to the second equation:


2(X+5Y=10)
-2X-10Y=-20


2X+10Y=20
-2X-10Y=-20


The result is 0=0, which means that these equations are actually the SAME LINE.  The equations are therefore said to be "Dependent."
