5x-5y=20
\n" ); document.write( "5y-5x=-20
\n" ); document.write( "solve the system of equtions by graphing.
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Solve each equation for \"y\":
\n" ); document.write( "1st:
\n" ); document.write( "5x-5y=20
\n" ); document.write( "x-y = 4
\n" ); document.write( "y = x-4
\n" ); document.write( "----------------
\n" ); document.write( "2nd:
\n" ); document.write( "5y-5x=-20
\n" ); document.write( "y-x = -4
\n" ); document.write( "y = x-4
\n" ); document.write( "---------------
\n" ); document.write( "The two equations are the same so their graphs are the same line.
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cx-4%29\"$
\n" ); document.write( "-----------
\n" ); document.write( "Solution: All points of the form (x,x-4) where x is any Real Number.
\n" ); document.write( "-------
\n" ); document.write( "The system is described as being \"dependent\".
