You can put this solution on YOUR website!
if to choose x number of dogs and y number of kids, and x and y only whole non-negative numbers, then
\n" ); document.write( "\"4x%2B2y=30\"
\n" ); document.write( "\"2x%2By=15\"
\n" ); document.write( "\"y=-2x%2B15\"
\n" ); document.write( "Finding a good solution should be easy to do. Maybe try a graph to identify it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Would (2,11) work? It's on the line.
\n" ); document.write( "\"4%2A2%2B2%2A11\"
\n" ); document.write( "\"8%2B22\"
\n" ); document.write( "\"30\"----------yes. 2 dogs and 11 kids.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Can you find others which also work?
\n" ); document.write( "
