let k = Katie's age now
\n" ); document.write( "Let a = Anne's age now
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"Four years ago, Katie was twice as old as Anne was then.\"
\n" ); document.write( "k - 4 = 2(a-4)
\n" ); document.write( "k - 4 = 2a - 8
\n" ); document.write( "k = 2a - 8 + 4
\n" ); document.write( "k = 2a - 4
\n" ); document.write( ":
\n" ); document.write( "\"In 6 years, Anne will be the same age that Katie is now.
\n" ); document.write( "a + 6 = k
\n" ); document.write( ":
\n" ); document.write( "Replace k with (a+6) in the 1st equation
\n" ); document.write( "a + 6 = 2a - 4
\n" ); document.write( "6 + 4 = 2a - a
\n" ); document.write( "10 = a
\n" ); document.write( ":
\n" ); document.write( "Anne is 10, Kate is 16
