.30x+.10(100-x)=.12*100
\n" ); document.write( ".30x+10-.10x=12
\n" ); document.write( ".20x=12-10
\n" ); document.write( ".20x=2
\n" ); document.write( "x=2/.2
\n" ); document.write( "x=10 gallons of 30% solution is used.
\n" ); document.write( "100-10=90 gallons 0f 10% is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".30*10+.10*90=.12*100
\n" ); document.write( "3+9=12
