You can put this solution on YOUR website!
You first need to \"translate\" the english equation to an mathematical equation.
\n" ); document.write( "You should get something that looks like this:
\n" ); document.write( " $\"20-X=42\"$
\n" ); document.write( "You want the X by itself, so you MUST substract 20 from both sides
\n" ); document.write( " $\"-X=22\"$
\n" ); document.write( "Since -X=22, then that means X=-22\r
\n" ); document.write( "\n" ); document.write( "*CHECK*
\n" ); document.write( " $\"20-%28-22%29=42\"$
\n" ); document.write( "If you subtract a negative, you a basically adding it.
\n" ); document.write( " $\"20%2B22=42\"$
\n" ); document.write( " $\"42=42\"$
\n" ); document.write( "Since the last equation is true, your answer is true.
\n" ); document.write( "Hope this helps! \n" ); document.write( "
