You can put this solution on YOUR website!
Let $\"+x+\"$ = oz of 50% antifreeze solution needed
\n" ); document.write( " $\"+.5x+\"$ = oz of antifreeze in 50% antifreeze solution
\n" ); document.write( " $\"+.8%2A10+=+8+\"$ oz of antifreeze in 80% antifreeze solution
\n" ); document.write( "-------------
\n" ); document.write( " $\"+%28+.5x+%2B+8+%29+%2F+%28+x+%2B+10+%29+=+.6+\"$
\n" ); document.write( " $\"+.5x+%2B+8+=+.6%2A%28+x+%2B+10+%29+\"$
\n" ); document.write( " $\"+.5x+%2B+8+=+.6x+%2B+6+\"$
\n" ); document.write( " $\"+.1x+=+2+\"$
\n" ); document.write( " $\"+x+=+20+\"$
\n" ); document.write( "20 oz of 50% antifreeze solution is needed
\n" ); document.write( "check answer:
