You can put this solution on YOUR website!
s = Sam's present age
\n" ); document.write( "d = Dan's
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( "\" four years ago Samantha was 3 times as old as Danny.\"
\n" ); document.write( "s - 4 = 3(d - 4)
\n" ); document.write( "s - 4 = 3d - 12
\n" ); document.write( "s = 3d - 12 + 4
\n" ); document.write( "s = 3d - 8
\n" ); document.write( ":
\n" ); document.write( "\"Four years from now, Samantha will be only twice as old as Danny.\"
\n" ); document.write( "s + 4 = 2(d + 4)
\n" ); document.write( "s + 4 = 2d + 8
\n" ); document.write( "s = 2d + 8 - 4
\n" ); document.write( "s = 2d + 4
\n" ); document.write( ":
\n" ); document.write( "How old are they now
\n" ); document.write( "s = s so we can write the equations as
\n" ); document.write( "3d - 8 = 2d + 4
\n" ); document.write( "3d - 2d = 8 + 4
\n" ); document.write( "d = 12 yrs is Dan's present age
\n" ); document.write( "I'll let you find s, check solutions in both statements \n" ); document.write( "
\n" );
