Hi there,
\n" ); document.write( "Melodyis three times as old as jaypee.
\n" ); document.write( "M = 3J
\n" ); document.write( "Ten years ago she was eight times as old as jaypee.
\n" ); document.write( "M - 10 = 8(J - 10)
\n" ); document.write( "Replace M with 3J from top equation.
\n" ); document.write( "3J - 10 = 8(J - 10)
\n" ); document.write( "3J - 10 = 8J - 80
\n" ); document.write( "Collect like terms.
\n" ); document.write( "3J - 8J = -80 + 10
\n" ); document.write( "-5J = -70
\n" ); document.write( "5J = 70
\n" ); document.write( "J = 14
\n" ); document.write( "Melodyis is 42 years old
\n" ); document.write( "Jaypee is 14 years old.
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
