(i) $\"x+-+y+=+13\"$
\n" ); document.write( "(ii) $\"3x+%2B+2y+=+129\"$
\n" ); document.write( "step 1 - multiply (i) by -3 to get
\n" ); document.write( "(iii) $\"-3x+%2B+3y+=+-39\"$
\n" ); document.write( "step 2 - add (ii) and (iii) to get
\n" ); document.write( "(iv) $\"5y+=+90\"$
\n" ); document.write( "step 3 - divide by 4 to get
\n" ); document.write( "(v) $\"y+=+18\"$
\n" ); document.write( "so this means that
