.90*3=.17(3+x)
\n" ); document.write( "2.7=.51+.17x
\n" ); document.write( "-.17x=.51-2.7
\n" ); document.write( "-.17x=-2.15
\n" ); document.write( "x=-2.15/-.17
\n" ); document.write( "x=12.88 pints of water are added.
\n" ); document.write( "Proof:
\n" ); document.write( ".90*3=.17(3+12.88)
\n" ); document.write( "2.7=.17*15.88
