Hi there,
\n" ); document.write( "Elizabeth is seven years older than Chloe.
\n" ); document.write( "E = 7 + C......(1)
\n" ); document.write( "Four years ago, Elizabeth was twice as old as Chloe was.
\n" ); document.write( "E - 4 = 2(C - 4).....(2)
\n" ); document.write( "Replace 'E' in Eq(2) with '7 + C' from Eq(1)
\n" ); document.write( "7 + C - 4 = 2(C - 4)
\n" ); document.write( "7 + C - 4 = 2C - 8
\n" ); document.write( "Collect like terms.
\n" ); document.write( "C - 2C = - 8 + 4 - 7
\n" ); document.write( "- C = - 11
\n" ); document.write( "Multiply both sides by -1
\n" ); document.write( "C = 11
\n" ); document.write( "Elizabeth is 18 years old
\n" ); document.write( "Chloe is 11 years old.
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
\n" );
