.10x+.05*2=.07(x+5)
\n" ); document.write( ".10x+.1=.07x+.35
\n" ); document.write( ".10x-.07x=.35-.1
\n" ); document.write( ".03x=.25
\n" ); document.write( "x=.25/.03
\n" ); document.write( "x=8.333 Liters of 10% acid is used.
\n" ); document.write( "Proof:
\n" ); document.write( ".10*8.333+.05*2=.07(8.333+5)
