percent percentage ---------------- quantity
\n" ); document.write( "Acid type I 2 ---------------- x ml
\n" ); document.write( "Acid type II 5 ---------------- 24 - x ml
\n" ); document.write( "Mixture 4.00% ---------------- 24
\n" ); document.write( "
\n" ); document.write( "2x+5(24-x)=4*24
\n" ); document.write( "2x+120-5x=96
\n" ); document.write( "2x-5x=96-120
\n" ); document.write( "-3x=-24
\n" ); document.write( "/-3
\n" ); document.write( "x=8ml 2.00% Acid type I
\n" ); document.write( "16 ml 5.00% Acid type II
\n" ); document.write( "
\n" ); document.write( "
\n" );
