Let n be the required number. From the problem description, you can write:
\n" ); document.write( " $\"%28n%2F5%29%2B%28n%2F15%29%2B%28n%2F50%29+=+43\"$ Add the fractions, the LCD is 150.
\n" ); document.write( " $\"%2830n%2B10n%2B3n%29%2F150+=+43\"$ Simplify.
\n" ); document.write( " $\"43n%2F150+=+43\"$ Multiply both sides by 150.
\n" ); document.write( " $\"43n+=+43%28150%29\"$ Divide both sides by 43.
\n" ); document.write( " $\"n+=+150\"$ \n" ); document.write( "

\n" );
