the sum of 3*x and 7 more than x = the difference between -11 and twice x
\n" ); document.write( "3*x+(x+7)=-11-2x
\n" ); document.write( "3x+x+7=-11-2x
\n" ); document.write( "combine like terms
\n" ); document.write( "4x+7=-11-2x
\n" ); document.write( "add 2x to both sides
\n" ); document.write( "6x+7=-11
\n" ); document.write( "subtract 7 from both sides
\n" ); document.write( "6x=-18
\n" ); document.write( "divide both sides by 6
\n" ); document.write( "x=-3 \n" ); document.write( "

\n" );
