\n" ); document.write( ":
\n" ); document.write( "Let x = no. years for Dad's age to be 4 times Tom's age
\n" ); document.write( ":
\n" ); document.write( "Then (17 - x) = Tom's age x years ago
\n" ); document.write( ":
\n" ); document.write( "And (50 - x) = Dad's age x years ago
\n" ); document.write( ":
\n" ); document.write( "\"how many years ago was the father four times as old as tom?\"
\n" ); document.write( " (50-x) = 4(17-x)
\n" ); document.write( " 50 - x = 68 - 4x
\n" ); document.write( " +4x -x = 68 - 50
\n" ); document.write( " 3x = 18
\n" ); document.write( " x = 18/3
\n" ); document.write( " x = 6 years ago, Dad was 4 times Tom's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution: 50 - 6 = 4(17 - 6) \n" ); document.write( "
