\n" ); document.write( "Let \"x\" be the amount of 100% solution you add.
\n" ); document.write( "---------------------------------
\n" ); document.write( "water + water = water
\n" ); document.write( "15 + 0*x = 0.98(15+x)
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "1500 + 0 = 98*15+98x
\n" ); document.write( "----
\n" ); document.write( "98x = 1500-1470
\n" ); document.write( "98x = 30
\n" ); document.write( "---
\n" ); document.write( "x = 30/98
\n" ); document.write( "---
\n" ); document.write( "x = 0.306 liters
