n+p = 21, so n = 21-p
\n" ); document.write( "4n+2p = 58
\n" ); document.write( "4(21-p)+2p = 58
\n" ); document.write( "84-4p+2p = 58
\n" ); document.write( "-2p = -26 Divide both sides by -2 and remember that -/- = +
\n" ); document.write( "p = 13 this is the pretzels, and the mix nuts:
\n" ); document.write( "n= 21-13 = 8
\n" ); document.write( "
