Let $\"+p+\"$ = the price of a plain cheese pizza
\n" ); document.write( "Let $\"+t+\"$ = the price of a single topping
\n" ); document.write( "-------------------
\n" ); document.write( "(1) $\"+p+%2B+3t+=+1535+\"$
\n" ); document.write( "(2) $\"+p+%2B+5t+=+1795+\"$ ( in cents )
\n" ); document.write( "----------------------------
\n" ); document.write( "Subtract (1) from (2)
\n" ); document.write( " $\"+2t+=+260+\"$
\n" ); document.write( " $\"+t+=+130+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+p+%2B+3%2A130+=+1535+\"$
\n" ); document.write( "(1) $\"+p+=+1535+-+390+\"$
\n" ); document.write( "(1) $\"+p+=+1145+\"$
\n" ); document.write( "------------------
\n" ); document.write( "The price of a plain cheese pizza is $11.45
\n" ); document.write( "The price of a single topping is $1.30
\n" ); document.write( "------------------
\n" ); document.write( "check:
\n" ); document.write( "(2) $\"+p+%2B+5t+=+1795+\"$
\n" ); document.write( "(2) $\"1145+%2B+5%2A130+=+1795+\"$
\n" ); document.write( "(2) $\"+1145+%2B+650+=+1795+\"$
