[(120 / c)] / (c - 1) = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "120 / c = 4c - 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "30 = c^2 - c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0 = c^2 - c - 30 ___ 0 = (c - 6)(c + 5)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c - 6 = 0 ___ c = 6
\n" ); document.write( "
