(15/45)*60+x=.75(60+x)
\n" ); document.write( "1/3*60+x=45+.75x
\n" ); document.write( "20+x=45+.75x
\n" ); document.write( "x-.75x=45-20
\n" ); document.write( ".25x=25
\n" ); document.write( "x=25/.25
\n" ); document.write( "x=100 ounces of pure turpentine needs to be added for a 75% solution.proof
\n" ); document.write( "20+100=45+(.75*100)
\n" ); document.write( "120=45+75
