Currently Karen is 4 times as old as Lucy. Six years from now, Karen will be 3 times as old as Lucy.
\n" ); document.write( " How old is Lucy now?
\n" ); document.write( ":
\n" ); document.write( "Let's do it this way
\n" ); document.write( ":
\n" ); document.write( "Let L = Lucy's age now
\n" ); document.write( "Let K = Karen's age now
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( "\"Karen is 4 times as old as Lucy.\"
\n" ); document.write( "K = 4L
\n" ); document.write( ":
\n" ); document.write( "\"Six years from now, Karen will be 3 times as old as Lucy\"
\n" ); document.write( "K + 6 = 3(L + 6)
\n" ); document.write( "K + 6 = 3L + 18
\n" ); document.write( "K = 3L + 18 - 6
\n" ); document.write( "K = 3L + 12
\n" ); document.write( "Replace K with 4L (from the 1st statement)
\n" ); document.write( "4L = 3L + 12
\n" ); document.write( "4L - 3L = 12
\n" ); document.write( "L = 12 yrs is Lucy's age now
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check our solution in the given statement: (Karen = 4(12) = 48)
\n" ); document.write( "\"Six years from now, Karen will be 3 times as old as Lucy\"
\n" ); document.write( "48 + 6 = 3(12+6)
\n" ); document.write( "54 = 3(18)
\n" ); document.write( "
\n" );
