$\"D\"$ - Tom's dad's age
\n" ); document.write( " $\"T\"$ - Tom's age
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( " $\"D=4%2B2T\"$ <---Tom's dad is 4 years older than twice Tom's age
\n" ); document.write( " $\"D=40\"$ <--- Tom's dad is 40
\n" ); document.write( "So then substituting,
\n" ); document.write( " $\"40=4%2B2T\"$ <--- They both equal D set them equal to each other.
\n" ); document.write( " $\"2T=36\"$ <--- Subtract 4 from both sides
\n" ); document.write( " $\"T=18\"$ <--- Divide both sides by 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
