Justine is 15years older than Emily now, but in 6 years time she will be twice as old as Emily.
\n" ); document.write( "----------------
\n" ); document.write( "The age difference will always be 15 years.
\n" ); document.write( "--> 15 & 30 are 2x
\n" ); document.write( "Subtract 6
\n" ); document.write( "==============
\n" ); document.write( "J + 6 = 2(E + 6)
\n" ); document.write( "J = E + 15
\n" ); document.write( "---
\n" ); document.write( "E + 15 + 6 = 2(E + 6) = 2E + 12
\n" ); document.write( "--> E = 9, J = 24
\n" ); document.write( "
\n" );
