That's right:
\n" ); document.write( ":
\n" ); document.write( "2(4x-8) + x = 29
\n" ); document.write( ":
\n" ); document.write( "8x - 16 + x = 29
\n" ); document.write( ":
\n" ); document.write( "9x = 45
\n" ); document.write( ":
\n" ); document.write( "x = 5
\n" ); document.write( ":
\n" ); document.write( "Check 4(5)-8 = 12; 12 + 12 + 5 = 29
\n" ); document.write( "
\n" ); document.write( "
\n" );
