From the problem description, you can write: (n = the missing number)
\n" ); document.write( "2(3n-12) = -42 \"If 12 is subtracted from 3 times a number (3n-12) and the difference is multiplied by 2, (2(3n-12)) the result is (=) -42\"
\n" ); document.write( "Simplify and solve for n.
\n" ); document.write( "2(3n-12) = -42 Apply the distributive property to the left side.
\n" ); document.write( "6n-24 = -42 Add 24 to both sides.
\n" ); document.write( "6n = -18 Finally, divide both sides by 6.
\n" ); document.write( "n = -3 \n" ); document.write( "

\n" );
