I had to make up a word problem and solve by using a rational equation.. but I'm confused on how to solve it. My problem is- It takes an inexperienced painter 12 hours to paint a whole house, while it only takes a professional painter 6 hours to get it done. How long would it take for both the inexperienced painter and professional painter to paint the house, if they painted it together?

I know it would be 1/12+1/6=1/x... but what next?
