\n" ); document.write( "Katty is one fifth as old as Melinda. In four years three times Katty's age will equal Melinda's age. Find Melinda's age now.
\n" ); document.write( "
Let Melinda's age, be M	
\n" );
document.write( "Then Katty's is: \"matrix%281%2C3%2C+%281%2F5%29+%2A+M%2C+or%2C+M%2F5%29\"
\n" );
document.write( "We then get: \"3%28M%2F5+%2B+4%29+=+M\"	
\n" );
document.write( "\"3M%2F5+%2B+12+=+M\"	
\n" );
document.write( "3M + 60 = 5M ------ Multiplying by LCD, 5	
\n" );
document.write( "60 = 5M - 3M	
\n" );
document.write( "M, or Melinda is: \"highlight_green%28matrix%281%2C4%2C+60%2F2%2C+or%2C+30%2C+years-old%29%29\"
\n" );
document.write( "This is based on: \"In four years three times Katty's age will equal Melinda's\" CURRENT age
\n" );
document.write( "If it's, \"In four years three times Katty's age will equal Melinda's\" AGE THEN, then Melinda is now 20 years-old. \n" );
document.write( "
\n" );
