You can put this solution on YOUR website!
\"h%28x%29+=+%28f%2Bg%29%28x%29\"
\n" ); document.write( "\"f%28x%29+=+2x%2B1\" and \"g%28x%29+=+x%2B2\", so
\n" ); document.write( "\"%28f%2Bg%29%28x%29+=+%282x%2B1%29%2B%28x%2B2%29\" = \"3x%2B3\"
\n" ); document.write( "\"h%28x%29+=+3x%2B3\"
\n" ); document.write( "Now you want to set h(x) = to each of the numbers in your list, solve for x, then select the corresponding letter of the alphabet. I'll do the first few to get you started:
\n" ); document.write( "First letter:
\n" ); document.write( "\"3x%2B3+=+21\" Subtract 3 from both sides.
\n" ); document.write( "\"3x+=+18\" Divide both sides by 3.
\n" ); document.write( "\"x+=+6\" The 6th letter of the alphabet is F. This is the first letter of the message.
\n" ); document.write( "2nd letter:
\n" ); document.write( "\"3x%2B3+=+30\"
\n" ); document.write( "\"3x+=+27\"
\n" ); document.write( "\"x+=+9\" The 9th letter of the alphabet is I. This is the second letter of the message.
\n" ); document.write( "3rd letter:
\n" ); document.write( "\"3x%2B3+=+45\"
\n" ); document.write( "\"3x+=+42\"
\n" ); document.write( "\"x+=+14\" The 14th letter of the alphabet is N. This is the 3rd letter of the message.\r
\n" ); document.write( "\n" ); document.write( "You should be able to finish this yourself.
\n" ); document.write( "If you are still having trouble, re-post the problem.
