<PRE><B>Question 218401</B>
System by graphing
2x+y=10
6x+3y=30 or 2x+y=10 after dividing by 3 to both sides of the equation.  They are not independent and are the same line.  Hence, there are many solutions satisfying the equations.


Here are the two graphs:


{{{graph(600,600, -15,15, -15,15, -2x+10, -6x/3+30/3)}}}


I hope the above steps were helpful.
