You can put this solution on YOUR website!
Let v = video and d = dvd
\n" ); document.write( "---
\n" ); document.write( "from the given we get
\n" ); document.write( " (i) \"6v+%2B+12d+=+35.10\"
\n" ); document.write( "(ii) \"8v+%2B+3d+=+27.95\"
\n" ); document.write( "step 1 - multiply (ii) by -4 to get
\n" ); document.write( "(iii) \"-32v+-12d+=+-111.80\"
\n" ); document.write( "step 2 - add (ii) and (iii) to get
\n" ); document.write( "(iv) \"-26v+=+-76.70\"
\n" ); document.write( "divide by -26 to get
\n" ); document.write( "(v) \"v+=+2.95\"
\n" ); document.write( "and then
\n" ); document.write( "(vi) \"d+=+1.45\"
\n" ); document.write( "
\n" );
