\n" ); document.write( " $\"V=+-20t+%2B+250\"$ \r
\n" ); document.write( "\n" ); document.write( "If $\"+V\"$ = $ $\"150\"$ , then:\r
\n" ); document.write( "\n" ); document.write( " $\"150=+-20t+%2B+250\"$ ЕЕ..move $\"-20t\"$ to the left, and $\"150\"$ to the right\r
\n" ); document.write( "\n" ); document.write( " $\"20t+=+250+-+150\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"20t+=++100\"$ ..divide both sides by $\"20\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"t+=+5\"$ \r
\n" ); document.write( "\n" ); document.write( "the value of the software is $ $\"150\"$ after $\"+5\"$ years \r
