You can put this solution on YOUR website!
c= number of chocolate cones sold
\n" ); document.write( "v= number of vanilla cones sold
\n" ); document.write( "\"The number of chocolate cones sold was 1 more than 4 times the number of vanilla cones sold\" means that c was 1 more than \"4v\", or
\n" ); document.write( "\"c=4v%2B1\"
\n" ); document.write( "If only chocolate and vanilla cones are sold, and the total sold was 121, it means that
\n" ); document.write( "\"c%2Bv=121\"
\n" ); document.write( "The two equations form the system of equations
\n" ); document.write( "\"system%28c=4v%2B1%2Cc%2Bv=121%29\"
\n" ); document.write( "That system asks to be solved by substitution,
\n" ); document.write( "According to the first equation, the expression \"4v%2B1\" is equal to c,
\n" ); document.write( "so you substitute that expression for c in the second equation and get
\n" ); document.write( "\"4v%2B1%2Bv=121%29\" --> \"5v%2B1=121\" --> \"5v%2B1-1=121-1\" --> \"5v%2F5=120%2F5\" --> \"highlight%28v=24%29\"
\n" ); document.write( "Then you substitute that value into \"c=4v%2B1\" to get
\n" ); document.write( "\"c=4%2A24%2B1\" --> \"c=96%2B1\" --> \"highlight%28c=97%29\"
\n" ); document.write( "
\n" );
