\n" ); document.write( "subtract 15 from both sides
\n" ); document.write( "5=5f
\n" ); document.write( "1=f
\n" ); document.write( "but anyways
\n" ); document.write( "20=5f+15
\n" ); document.write( "20-5f+15
\n" ); document.write( "-5f=-5
\n" ); document.write( "f=1\r
\n" ); document.write( "\n" ); document.write( "negative
\n" ); document.write( "you subtract 5f from both sides
\n" ); document.write( "you want 0 instead of 5f so you have to subtract
\n" ); document.write( "if you added 5f you get
\n" ); document.write( "20+5f=5f+5f+15
\n" ); document.write( "20+5f=10f+15
