l - s = 23. This is the same as s = l-23.
\n" ); document.write( " $\"l%2F3+%2B+3s+=+81\"$ . By direct substitution,
\n" ); document.write( " $\"l%2F3+%2B+3%28l-23%29+=+81\"$ ,
\n" ); document.write( " $\"l%2F3+%2B+3l+-+69+=+81\"$ ,
\n" ); document.write( " $\"l%2F3+%2B+3l+=+150\"$ ,
\n" ); document.write( " $\"%28l%2B9l%29%2F3+=+150\"$ ,
