You can put this solution on YOUR website!
I made the correction below with what I think you meant.
\n" ); document.write( " $\"9a%2B6b=-9\"$
\n" ); document.write( " $\"-9a%2Bb=30\"$
\n" ); document.write( "Add the equations together.
\n" ); document.write( " $\"9a%2B6b-9a%2Bb=-9%2B30\"$
\n" ); document.write( " $\"7b=21\"$
\n" ); document.write( " $\"b=3\"$
\n" ); document.write( "Then use either equation to solve for $\"a\"$
\n" ); document.write( " $\"9a%2B18=-9\"$
\n" ); document.write( " $\"9a=-27\"$
\n" ); document.write( " $\"a=-3\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
