\n" ); document.write( "\n" ); document.write( " $\"2%28x%2B3%29=9%2Bx\"$ ....first multiply $\"2%28x%2B3%29\"$ \r

\n" ); document.write( "\n" ); document.write( " $\"2x%2B6=9%2Bx\"$ ....now isolate variable $\"x\"$ ; add $\"-x\"$ to both sides\r

\n" ); document.write( "\n" ); document.write( " $\"2x-x%2B6=9%2Bx-x\"$ ...cancel $\"x\"$ and $\"-x\"$ on right side\r
