The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12
The answer to your question is C40
Divide 914/420, move the decimal over to the right two places and you'll get approximately 217.5%
EDIT: My mistake, read question wrong.


<u></u>117.62%
Subtract the difference and divide by original number (: Move decimal place over two places.
Step 1. Combine like terms
Step 2. Subtract 7 from both sides
Step 3. Divide 6 from both sides
Final answer: x=1/6
