\n" ); document.write( "Amy is one third the age of her mother.\r
\n" ); document.write( "\n" ); document.write( " In 12 years time, Amy will be half the age of her mother.\r
\n" ); document.write( "\n" ); document.write( "How old is Amy’s mother?
\n" ); document.write( "
Let Amy's mother's age be M
\n" );
document.write( "Then Amy's = \"matrix%281%2C3%2C+%281%2F3%29M%2C+or%2C+M%2F3%29\"
\n" );
document.write( "We then get: 
\n" );
document.write( "2M + 72 = 3(M + 12) -------- Multiplying by LCD, 6
\n" );
document.write( "2M + 72 = 3M + 36
\n" );
document.write( "2M - 3M = 36 - 72
\n" );
document.write( "- M = - 36
\n" );
document.write( "Amy's mother, or:  \n" );
document.write( "
