\n" ); document.write( "\n" ); document.write( " $\"x%2F-9=-3\"$ ...as you can see $\"x\"$ is divided by negative number $\"-9\"$ ,and since we need eliminate $\"-9\"$ from denominator and get $\"x\"$ , we will multiply $\"x%2F-9\"$ by $\"-9\"$ because $\"%28-9x%29%2F-9=%28-9%2F-9%29x=x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-9%28x%2F-9%29=-9%28-3%29\"$ , so, when we multiply left side by $\"-9\"$ we do same with right side and equation will not change its value\r
\n" ); document.write( "\n" ); document.write( " $\"cross%28-9%29%28x%2Fcross%28-9%29%29=27\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=27\"$ \n" ); document.write( "
