Answer by Edwin McCravy(8909)   (Show Source): You can put this solution on YOUR website! Is the answer x=0.28,14.28 I don't think that's right ``` Checkley said yes, so let's find out for sure: with , , Using the +, Using a calculator: That rounds off to 0.28, so you're right on that one. Using the -, Using a calculator: That rounds off to -14.28. Uh oh! You missed the sign on that one. Checkley didn't notice. But you were half right! Edwin```
