Let x=ounces of 30% sugar soln., 50-x=ounces of 40% sugar soln.
\n" ); document.write( ".
\n" ); document.write( ".3x+.4(50-x)=.34*50
\n" ); document.write( ".3x+20-.4x=17
\n" ); document.write( "-.1x+20-20=17-20
\n" ); document.write( "-.1x=-3
\n" ); document.write( "-.1x/-.1=-3/.1
\n" ); document.write( "x=30 oz of 30% sugar soln.
\n" ); document.write( "20 oz of 40% sugar soln.
\n" ); document.write( "Always check:
\n" ); document.write( "30*.3+20*.4=.34*50 true.
