You can put this solution on YOUR website!
Let m = Michael's age now
\n" ); document.write( "Let t = toms age now
\n" ); document.write( ";
\n" ); document.write( "write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"michael is 4 years older than tom.\"
\n" ); document.write( "m = t + 4
\n" ); document.write( ":
\n" ); document.write( "\"5 years ago michael was twice toms age\"
\n" ); document.write( "m - 5 = 2(t - 5)
\n" ); document.write( ":
\n" ); document.write( "m - 5 = 2t - 10
\n" ); document.write( ";
\n" ); document.write( "Replace m with (t+4); find t
\n" ); document.write( "(t+4) - 5 = 2t - 10
\n" ); document.write( ";
\n" ); document.write( "t - 1 = 2t - 10
\n" ); document.write( ":
\n" ); document.write( "-1 + 10 = 2t - t
\n" ); document.write( ":
\n" ); document.write( "t = 9 yrs is Tom's age now
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement: (m = 13)
\n" ); document.write( " \"5 years ago michael was twice toms age\"
\n" ); document.write( "13 - 5 = 2(9 - 5)
\n" ); document.write( " \n" ); document.write( "

\n" );
