1. $\"3c-2d=13\"$
\n" ); document.write( "2. $\"2c%2B3d=0\"$
\n" ); document.write( "From eq. 2,
\n" ); document.write( " $\"2c=-3d\"$
\n" ); document.write( "Mutliply both sides by 3.
\n" ); document.write( " $\"6c=-9d\"$
\n" ); document.write( "Multiply eq. 1 by 2,
\n" ); document.write( " $\"6c-4d=26\"$
\n" ); document.write( "Now substitute for $\"6c\"$ ,
\n" ); document.write( " $\"-9d-4d=26\"$
\n" ); document.write( " $\"-13d=26\"$
\n" ); document.write( " $\"highlight%28d=-2%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"2c=-3d\"$
\n" ); document.write( " $\"2c=-3%28-2%29\"$
\n" ); document.write( " $\"highlight%28c=3%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
