(1/6+1/4=1/x )= 4x+6x=24 = change the denominators to a common, and just solve the equation.

We CAN just tell you the answer, but then we feel like you're not learning anything. You wouldn't want that now, would you?

anonymous · Answer

Yeah actually i would. :D

Well, if you wait around you'll eventually find those tutors who just want medals, so you'll have to hold out for that. I suggest you at least try to solve
4x+6x=24
Please show us your work, and if you get it wrong we usually have no problem explaining where you made your mistake.

That's cute. If you want to know the grown-up way to cheat like that use WolframAlpha, It can do all kinds of that stuff. I do wish I could revoke your medal though :/
