Solve:
\n" ); document.write( " $\"12y%2B7+=+21y\"$ First, collect the y's on one side of the equation by subtracting 12y from both sides.
\n" ); document.write( " $\"12y-12y%2B7+=+21y-12y\"$ Evaluate this.
\n" ); document.write( " $\"7+=+9y\"$ Now divide both sides by 9 to get the y by itself.
\n" ); document.write( " $\"7%2F9+=+cross%289%29y%2Fcross%289%29\"$ Cancel the 9's on the right side.
\n" ); document.write( " $\"7%2F9+=+y\"$ or $\"highlight%28y+=+7%2F9%29\"$ \n" ); document.write( "

\n" );
