\n" ); document.write( "1. A number: let it be $\"x\"$
\n" ); document.write( "2.times 2: will be $\"2x\"$
\n" ); document.write( "3.increased by 7:will be $\"2x%2B7\"$
\n" ); document.write( "4.is 31: $\"2x%2B7=31\"$ equation\r
\n" ); document.write( "\n" ); document.write( " $\"2x%2B7=31\"$ .........solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x=31-7\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x=24\"$ \r
