You can put this solution on YOUR website!
Let d=hotdogs; h=hamburger
\n" ); document.write( "The two equations are
\n" ); document.write( "2d+h=3.39
\n" ); document.write( "3d+3h=6.57
\n" ); document.write( "You can use the substitution method to solve this. Take the first equation and solve for h. The equation for that is:
\n" ); document.write( "h=-2d+3.39
\n" ); document.write( "Susbstitute that into the second equation
\n" ); document.write( "3d+3(-2d+3.39)=6.57
\n" ); document.write( "3d-6d+10.17=6.57
\n" ); document.write( "-3d=-3.6
\n" ); document.write( "d=1.2
\n" ); document.write( "The cost of one hotdog is $1.20
\n" ); document.write( "
\n" );
