\n" ); document.write( "Dad is 6 times as old as Michael
\n" ); document.write( "d = 6m
\n" ); document.write( ":
\n" ); document.write( " and he will be 4 times as old as Michael in 4 years time.
\n" ); document.write( "d + 4 = 4(m+4)
\n" ); document.write( "d + 4 = 4m + 16
\n" ); document.write( "d = 4m + 16 - 4
\n" ); document.write( "d = 4m + 12
\n" ); document.write( "replace d with 6m
\n" ); document.write( "6m = 4m + 12
\n" ); document.write( "6m - 4m = 12
\n" ); document.write( "2m = 12
\n" ); document.write( "m = 6 yrs is M's age
