\n" ); document.write( "In 10 years, the sum of their age, will be 44 translates to
\n" ); document.write( "(ii) $\"M+%2B+10+%2B+A+%2B+10+=+44\"$
\n" ); document.write( "by substitution of (i) into (ii) we get
\n" ); document.write( "(iii) $\"2A+%2B+10+%2B+A+%2B+10+=+44\"$
\n" ); document.write( "we get
\n" ); document.write( " $\"3A+%2B+20+=+44\"$
\n" ); document.write( " $\"3A+=+24\"$
\n" ); document.write( " $\"A+=+8\"$
