13w + 30s = 20v
\n" ); document.write( "w = 40
\n" ); document.write( "v = w + s
\n" ); document.write( "v = 40 + s
\n" ); document.write( "---
\n" ); document.write( "13w + 30s = 20v
\n" ); document.write( "13(40) + 30s = 20(40 + s)
\n" ); document.write( "520 + 30s = 800 + 20s
\n" ); document.write( "10s = 280
\n" ); document.write( "s = 28
\n" ); document.write( "---
\n" ); document.write( "28 gallons of 30% kiwi juice
