Six times the difference between two and a number is ten

It is a tricky question. Only hard part is understanding the word problem and then converting it into numbers. Let us concentrate on the problem now.

Let us assume the unknown number = x

The coming to the equation part, we get

6 (2 - x) = 10

12 - 6x = 10

-6x = 10 - 12

-6x = - 2

x = 2/6

= 1/3

So the unknown number is 1/3. I hope i have solved the question to your satisfaction and in future you can do this type of problems by yourself.
