Here are the original; equations:
\n" ); document.write( "(i) \"5x+-+%282%2F5%29y+=+28+\"
\n" ); document.write( "(ii) \"2x+%2B+%283%2F2%29y+=+39%2F2\"
\n" ); document.write( "Since you are not a fan of fractions, multiply (i) by 5 and then (ii) by 2 to get
\n" ); document.write( "(iii) \"25x+-+2y+=+140\"
\n" ); document.write( "(iv) \"4x+%2B+3y+=+39\"
\n" ); document.write( "Now multiply (iii) by 3 and (iv) by 2 to get
\n" ); document.write( "(v) \"75x+-+6y+=+420\"
\n" ); document.write( "(vi) \"8x+%2B+6y+=+78\"
\n" ); document.write( "add down and solve for x.
\n" ); document.write( "\"83x+=+498\"
\n" ); document.write( "\"x+=+6\"
\n" ); document.write( "Now find y.
\n" ); document.write( "\"y+=+5\"
\n" ); document.write( "(6,5)
\n" ); document.write( "
\n" );
