1. $\"5x-y=13\"$
\n" ); document.write( "2. $\"5x%2B6y=-8\"$
\n" ); document.write( "Subtract eq. 1 from eq. 2,
\n" ); document.write( " $\"5x%2B6y-5x%2By=-8-13\"$
\n" ); document.write( " $\"7y=-21\"$
\n" ); document.write( " $\"highlight%28y=-3%29\"$
\n" ); document.write( "Then use either equation to solve for $\"x\"$ ,
\n" ); document.write( " $\"5x%2B3=13\"$
\n" ); document.write( " $\"5x=10\"$
\n" ); document.write( " $\"highlight%28x=2%29\"$
\n" ); document.write( "The system has one solution and is consistent and independent. \n" ); document.write( "
