You can put this solution on YOUR website!
m = the man's present age
\n" ); document.write( "s = the son's
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( " A man is 5 times as old as his son.
\n" ); document.write( "m = 5s
\n" ); document.write( " Five years ago, the sum of their ages was 50.
\n" ); document.write( "(m-5) + (s-5) = 50
\n" ); document.write( "m + s - 10 = 50
\n" ); document.write( "m + s = 60
\n" ); document.write( ":
\n" ); document.write( " How old are they?
\n" ); document.write( "replace m with 5s in the 2nd equation
\n" ); document.write( "5s + s = 60
\n" ); document.write( "6s = 60
\n" ); document.write( "s = 60/6
\n" ); document.write( "s = 10 yrs is the son's present age
\n" ); document.write( "then
\n" ); document.write( "5(10) = 50 yrs is the man's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check the solution in the 2nd mattress
\n" ); document.write( "(50-5) + (10-5) = 50
\n" ); document.write( " \n" ); document.write( "

\n" );
