You can put this solution on YOUR website!
the goal is to get something that looks like x=(some number), so subtract 3x from both sides of the equation:
\n" ); document.write( "-17=7x-3x-9
\n" ); document.write( "-17=4x-9
\n" ); document.write( "then add 9 to both sides:
\n" ); document.write( "-17+9=4x
\n" ); document.write( "-8=4x
\n" ); document.write( "then divide both sides by 4
\n" ); document.write( "-2=x
\n" ); document.write( "so the solution is
\n" ); document.write( "x=-2
\n" ); document.write( "
\n" );
