x = pounds of cashews
\n" ); document.write( "---
\n" ); document.write( "5.30x + 1.60*10 = 3.30*(x + 10)
\n" ); document.write( "5.30x + 1.60*10 = 3.30x + 3.30*10
\n" ); document.write( "5.30x - 3.30x = 3.30*10 - 1.60*10
\n" ); document.write( "(5.30 - 3.30)x = 3.30*10 - 1.60*10
\n" ); document.write( "x = (3.30*10 - 1.60*10)/(5.30 - 3.30)
\n" ); document.write( "(3.30*10 - 1.60*10)/(5.30 - 3.30)
