1. $\"5x%2B7y=76\"$
\n" ); document.write( "2. $\"6x-8y=91\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"5x%2B7y=76\"$
\n" ); document.write( " $\"5x=-7y%2B76\"$
\n" ); document.write( " $\"x=%28-7y%2B76%29%2F5\"$
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( "2. $\"6x-8y=91\"$
\n" ); document.write( " $\"6%28-7y%2B76%29%2F5-8y=91\"$
\n" ); document.write( " $\"6%28-7y%2B76%29-40y=455\"$
\n" ); document.write( " $\"-42y%2B456-40y=455\"$
\n" ); document.write( " $\"-82y=-1\"$
\n" ); document.write( " $\"highlight%28+y=1%2F82%29\"$
\n" ); document.write( "Then use eq. 1,
\n" ); document.write( " $\"5x=-7y%2B76\"$
\n" ); document.write( " $\"5x=-7%2F82%2B76\"$
\n" ); document.write( " $\"5x=-7%2F82%2B6232%2F82\"$
\n" ); document.write( " $\"5x=6225%2F82\"$
\n" ); document.write( " $\"highlight%28+x=1245%2F82%29\"$ \n" ); document.write( "

\n" );
