\n" ); document.write( "Molly is 48 years old
\n" ); document.write( "Jill is 12 years old\r

\n" ); document.write( "\n" ); document.write( "============================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Work Shown:
\n" ); document.write( "M = Molly's age
\n" ); document.write( "J = Jill's age
\n" ); document.write( "Molly is 4 times old as Jill, meaning
\n" ); document.write( "Molly's age = 4*(Jill's age)
\n" ); document.write( "M = 4*J\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Their ages add to 60
\n" ); document.write( "M+J = 60
\n" ); document.write( "4J + J = 60 ... replace M with 4J
\n" ); document.write( "5J = 60
\n" ); document.write( "5J/5 = 60/5 ... divide both sides by 5
\n" ); document.write( "J = 12
\n" ); document.write( "Jill is 12 years old\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "M = 4*J
\n" ); document.write( "M = 4*12
\n" ); document.write( "M = 48
\n" ); document.write( "Molly is 48 years old\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "M+J = 60
\n" ); document.write( "48+12 = 60
\n" ); document.write( "60 = 60
\n" ); document.write( "The answers are confirmed.
