Hello,
\n" ); document.write( "First Describe the variables and write the equation:
\n" ); document.write( "VARIABLES: a=Adults 3a=Children so,
\n" ); document.write( "EQUATION: $\"a%2B3a=80\"$
\n" ); document.write( "

\n" ); document.write( "Now combine like terms:
\n" ); document.write( " $\"a%2B3a=4a\"$
\n" ); document.write( "

\n" ); document.write( "You are left with:
\n" ); document.write( " $\"4a=80+\"$ divide by 4
\n" ); document.write( "

\n" ); document.write( " $\"80%2F4=20\"$ SO, a=20 There were 20 Adults
\n" ); document.write( "

\n" ); document.write( "restate the eqation for the children
\n" ); document.write( " $\"C=3a\"$
\n" ); document.write( "

\n" ); document.write( "Plug in the numbers and multiply:
\n" ); document.write( " $\"3%2820%29=60\"$
\n" ); document.write( "

\n" ); document.write( "So, there were 20 Adults and 60 Children.
\n" ); document.write( "

\n" ); document.write( "TO CHECK ANSWER
\n" ); document.write( "restate the equation:
\n" ); document.write( " $\"a%2B3a=80\"$
\n" ); document.write( "Plug in the numbers:
\n" ); document.write( " $\"20%2B3%2820%29=80\"$
\n" ); document.write( "

\n" ); document.write( "Multiply:
\n" ); document.write( " $\"3%2820%29=60\"$
\n" ); document.write( "

\n" ); document.write( "You are left with:
\n" ); document.write( " $\"20%2B60=80\"$ now add 20+60
\n" ); document.write( "

\n" ); document.write( " $\"80=80\"$ Therefore the answer is correct.
\n" ); document.write( "
