the sum of a number and 3 is subtracted from 10 the result is 5.
\n" ); document.write( "10 - (n + 3) = 5
\n" ); document.write( "remove brackets, a neg outside changes the signs
\n" ); document.write( "10 - n - 3 = 5
\n" ); document.write( "-n + 7 = 5
\n" ); document.write( "-n = 5 - 7
\n" ); document.write( "-n = -2
\n" ); document.write( "therefore
\n" ); document.write( "n = 2 \n" ); document.write( "
