You can put this solution on YOUR website!
Assuming the marks indicate equal lengths:
\n" ); document.write( "12 - (3x-4) = 3x-4 - x
\n" ); document.write( "-3x + 16 = 2x - 4
\n" ); document.write( "5x = 20
\n" ); document.write( "x = 4 = GH
\n" ); document.write( "3x-4 = 8 = IJ
\n" ); document.write( "
\n" );
