1. $\"3x+%2B+y+=+26\"$
\n" ); document.write( "2. $\"-6x+%2B+y+=+-37\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"y=-3x%2B26\"$
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( " $\"-6x%2B%28-3x%2B26%29=-37\"$
\n" ); document.write( " $\"-9x%2B26=-37\"$
\n" ); document.write( " $\"-9x=-63\"$
\n" ); document.write( " $\"highlight%28x=7%29\"$
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( " $\"y=-3%287%29%2B26\"$
