Let's say the unknown number \"x\"
\n" ); document.write( "x + (-8) = x-8 \r
\n" ); document.write( "\n" ); document.write( "double the sum and make equal it to the 15 minus of the number:\r
\n" ); document.write( "\n" ); document.write( " 2*(x-8) = x-15\r
\n" ); document.write( "\n" ); document.write( "So: 2x-16 = x -15 >> x = 1.\r
\n" ); document.write( "\n" ); document.write( "RF.
\n" ); document.write( "
