\n" ); document.write( " $\"14x%2B3y=1\"$
\n" ); document.write( " $\"4x-y=4\"$ .........both sides multiply by $\"3\"$
\n" ); document.write( "------------------------------\r
\n" ); document.write( "\n" ); document.write( " $\"14x%2B3y=1\"$
\n" ); document.write( " $\"12x-3y=12\"$
\n" ); document.write( "---------------add\r
\n" ); document.write( "\n" ); document.write( " $\"14x%2B3y%2B12x-3y=1%2B12\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"26x=13\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=13%2F26\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=1%2F2\"$ \r
\n" ); document.write( "\n" ); document.write( "go to\r
\n" ); document.write( "\n" ); document.write( " $\"14x%2B3y=1\"$ , substitute $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"14%281%2F2%29%2B3y=1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"7%2B3y=1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3y=1-7\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3y=-6\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=-6%2F3\"$ \r
