You can put this solution on YOUR website!
x is the number so:

\n" ); document.write( "3 is added to a number x + 3
\n" ); document.write( "this sum is doubled 2(x + 3)
\n" ); document.write( "result is 2 more than the number = x + 2

\n" ); document.write( "So our formula is:
\n" ); document.write( " $\"+2%28x+%2B+3%29+=+x+%2B+2+\"$

\n" ); document.write( "Expand:
\n" ); document.write( " $\"+2x+%2B+cross%282%2A3%29%2B+6+=+x+%2B+2+\"$

\n" ); document.write( "Subtract 6 from each side:
\n" ); document.write( " $\"+2x+=+x+-+4+\"$

\n" ); document.write( "Subtract x from each side:
\n" ); document.write( " $\"+x+=+-4+\"$ and bob's your uncle! \n" ); document.write( "

\n" );
