Substituting,
\n" ); document.write( " $\"%284%2F3%29%282y-6%29%2B%285%2F6%29y=55\"$ \r
\n" ); document.write( "\n" ); document.write( "Multiply both sides by $\"6\"$ ,
\n" ); document.write( " $\"8%282y-6%29%2B5y=330\"$
\n" ); document.write( " $\"16y-48%2B5y=330\"$
\n" ); document.write( " $\"21y=378\"$
\n" ); document.write( " $\"y=18\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"x=2%2818%29-6\"$
\n" ); document.write( " $\"x=36-6\"$
\n" ); document.write( " $\"x=30\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
