let m = Mother's a age
\n" ); document.write( "let s = son's
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "The mother is eight more than twice the age of her son.
\n" ); document.write( "m = 2s + 8
\n" ); document.write( " Six years ago, she was four more than three times her son's age then.
\n" ); document.write( "m - 6 = 3(s - 6) + 4
\n" ); document.write( "m - 6 = 3s - 18 + 4
\n" ); document.write( "m = 3s - 18 + 6 + 4
\n" ); document.write( "m = 3s - 8
\n" ); document.write( "replace m with (2s+8) from the 1st statement
\n" ); document.write( "2s + 8 = 3s - 8
\n" ); document.write( "8 + 8 = 3s - 2s
\n" ); document.write( "16 = s
\n" ); document.write( "then
\n" ); document.write( "m = 2(16) + 8
\n" ); document.write( "m = 40
\n" ); document.write( ":
\n" ); document.write( " How old are they now. Mom's 40, son's 16
\n" ); document.write( " \n" ); document.write( "
\n" );
