Let your age be 'X'

Then the age of your brother will be

(1)/(3) x

The age of your sister is 10, but can also be written as an expression (since it is the age of your brother +6)

(1)/(3) x + 6

Now we get the following equation:

(1)/(3) x + 6 = 10

Subtract 6 from both sides

(1)/(3) x = 4

Multiply by 3

x = 12

Hence, the answer on your question (which is your age) is 12.
