$\"r=%28L-O%29%2F%28L%2BO%29\"$
\n" ); document.write( " $\"%28L%2BO%29%2Ar=cross%28L%2BO%29%2A%28L-O%29%2Fcross%28%28L%2BO%29%29\"$ Multiply both sides by $\"%28L%2BO%29\"$
\n" ); document.write( " $\"Lr%2BOr=L-O\"$ Distribute and simplify.
\n" ); document.write( "Get all L terms on one side, everything else on the other.
\n" ); document.write( " $\"Lr%2BOr-L=L-L-O\"$ Additive inverse of L.
\n" ); document.write( " $\"Lr-L%2BOr=-O\"$
\n" ); document.write( " $\"Lr-L%2BOr-Or=-O-Or\"$ Additive inverse of Or.
\n" ); document.write( " $\"L%2A%28r-1%29=-O%28r%2B1%29\"$ Distributive property.
\n" ); document.write( " $\"L%2A%28r-1%29%2F%28r-1%29=-O%28r%2B1%29%2F%28r-1%29\"$ Multiplicative inverse of (r-1).
\n" ); document.write( " $\"L=-O%28r%2B1%29%2F%28r-1%29\"$
\n" ); document.write( " $\"L=O%2A%28%281%2Br%29%2F%281-r%29%29\"$ \n" ); document.write( "

\n" );
