Do it like this one. Only the numbers are different.
\n" ); document.write( "-----------
\n" ); document.write( "Amanda wants to make 8 gal. of a 20% saline solution by mixing together a 56% saline solution and a 8% saline solution. How much of each solution must she use?
\n" ); document.write( "================
\n" ); document.write( "e = amount of 8%
\n" ); document.write( "f = amount of 56%
\n" ); document.write( "---
\n" ); document.write( "e+ f = 8 (total solution)
\n" ); document.write( "8e + 56f = 20*8 (total saline)
\n" ); document.write( "---
\n" ); document.write( "e+ f = 8
\n" ); document.write( "e + 7f = 20
\n" ); document.write( "------------ Subtract
\n" ); document.write( "-6f = -12
\n" ); document.write( "f = 2
\n" ); document.write( "e = 6
\n" ); document.write( "
\n" );
