Let's call the number N.
\n" ); document.write( "\"a number multipied by 8\"
\n" ); document.write( " $\"8%2AN\"$
\n" ); document.write( "\"added by 4'
\n" ); document.write( " $\"8%2AN%2B4\"$
\n" ); document.write( "\"is 7 more than a number\"
\n" ); document.write( " $\"8%2AN%2B4=N%2B7\"$
\n" ); document.write( " $\"8%2AN-N%2B4=N-N%2B7\"$ Subtract N from both sides.
\n" ); document.write( " $\"7%2AN%2B4=7\"$
\n" ); document.write( " $\"7%2AN%2B4-4=7-4\"$ Subtract 4 from both sides.
\n" ); document.write( " $\"7%2AN=3\"$
\n" ); document.write( " $\"7N%2F7=3%2F7\"$ Divide both sides by 7.
\n" ); document.write( " $\"N=3%2F7\"$ \n" ); document.write( "

\n" );
