Let J = the number of computers Julius sold and S = the number of computers Sam sold.
\n" ); document.write( "1) $\"J+=+5%2AS\"$ \"Julius sold 5 times as many computers as Sam sold...\"
\n" ); document.write( "2) $\"J%2BS+=+78\"$ \"In total, they sold 78 computers.\"
\n" ); document.write( "Substitute the J in eqation 1) into equation 2) and solve for S.
\n" ); document.write( "3) $\"%285%2AS%29%2BS+=+78\"$
\n" ); document.write( "3a) $\"6S+=+78\"$
\n" ); document.write( "3b) $\"S+=+13\"$ so:
\n" ); document.write( " $\"J+=+5%2813%29\"$
\n" ); document.write( " $\"J+=+65\"$
\n" ); document.write( "Julius sold 65 computers. \n" ); document.write( "
