Let $\"+x+\"$ = the unknown number
\n" ); document.write( " $\"+3%2A%28+x+-+5+%29+=+2x+%2B+3+\"$
\n" ); document.write( " $\"+3x+-+15+=+2x+%2B+3+\"$
\n" ); document.write( "Subtract $\"+2x+\"$ from both sides
\n" ); document.write( " $\"+x+-+15+=+3+\"$
\n" ); document.write( "Add $\"+15+\"$ to both sides
\n" ); document.write( " $\"+x+=+18+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+x+-+5+=+18+-+5+\"$
\n" ); document.write( " $\"+x+-+5+=+13+\"$
\n" ); document.write( " $\"+13%2A3+=+39+\"$
\n" ); document.write( "--------------------
\n" ); document.write( " $\"+2%2A18+=+36+\"$
\n" ); document.write( " $\"+36+%2B+3+=+39+\"$
\n" ); document.write( "OK \n" ); document.write( "
