$\"10p%2B5c=3.70\"$ multiply by a -2
\n" ); document.write( " $\"5p%2B10c=4.10\"$
\n" ); document.write( "_________________
\n" ); document.write( " $\"-20p-10c=-7.40\"$
\n" ); document.write( " $\"5p%2B10c=4.10\"$ add together
\n" ); document.write( " $\"-15p=-3.30\"$ divide by -15
\n" ); document.write( " $\"p=.22\"$
\n" ); document.write( " $\"5p%2B10c=4.10\"$
\n" ); document.write( " $\"5%28.22%29%2B10c=4.10\"$
