To solve this problem (isolate variable x) follow these steps:
\n" ); document.write( " $\"%28-3%2F8%29x%2B%285%2F56%29x=16\"$
\n" ); document.write( " $\"%28-21%2F56%29x%2B%285%2F56%29x=16\"$
\n" ); document.write( " $\"%28-16%2F56%29x=16\"$
\n" ); document.write( " $\"56%2A%28-16%2F56%29x=16%2A56\"$
\n" ); document.write( " $\"-16x=896\"$
\n" ); document.write( " $\"%28-16x%29%2F%28-16%29=%28896%2F-16%29\"$
\n" ); document.write( " $\"x=-56\"$
\n" ); document.write( "Here is what I did:
\n" ); document.write( "1. Copied the original problem. (correctly)
\n" ); document.write( "Since $\"%28-3%2F8%29x\"$ and $\"%285%2F56%29x\"$ where like terms (same varible, exponent, etc.) I found their LCD (Least Common Denominator)
\n" ); document.write( "2. I added them together.
\n" ); document.write( "3. Then, to isolate x I undid the current operation affecting x (multiplacation of -16) by dividing -16x by a -16.
\n" ); document.write( "3. And since we are solving for a variable, whatever we do to one side we must do to the other.
\n" ); document.write( "4. Then we simpliflfy. \n" ); document.write( "

\n" );
