\n" ); document.write( "-5z-3-4(z+1)=2z+6\r
\n" ); document.write( "\n" ); document.write( "I solved it and came up with -13/11. This however does not check.\r

\n" ); document.write( "-3[-6p+4-5(p-1)=-2p-5\r
\n" ); document.write( "\n" ); document.write( "I solved this and came up with -8/35. Again, this will not check.\r

\n" ); document.write( "2p=5(2p+5)\r
\n" ); document.write( "\n" ); document.write( "I solved this and came up with -8/25. And you guessed it, this did not check.\r
