$\"%281%2F2%29t+-+%281%2F5%29v+=+5%2F2\"$
\n" ); document.write( "Multiply both sides by $\"10\"$
\n" ); document.write( "1, $\"5t-2v=25\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"%282%2F3%29t+%2B+%281%2F4%29v+=+7%2F12\"$
\n" ); document.write( "Multiply both sides by $\"12\"$
\n" ); document.write( "2. $\"8t%2B3v=7\"$
\n" ); document.write( "Now multiply the first equation by 3 and the second by 2 and add them together to eliminate $\"v\"$ .
