A number is divisible by 9 if the sum of its digits is divisible by 9. For example, the number 19,836 is divisible by 9 but 19,825 is not.
If D767E89 is divisible by 9, where D and E each represent a single digit, what is the sum of all possible values of the sum D+E?

### Problem Statement
A binary string is a non-empty finite sequence of 0's and 1's. Given two binary strings, u and v, their concatenation, u * v, is defined to be the binary string obtained by appending v to the end of u. For example, if u = 01100 and v = 110, then u * v = 01100110.

# What is a general solution to the differential equation y'=2+2x^2+y+x^2y?
Jul 24, 2016
$y = C {e}^{x + {x}^{3} / 3} - 2$
#### Explanation:
$y ' = 2 + 2 {x}^{2} + y + {x}^{2} y$
this is separable,
$y ' = 2 \left(1 + {x}^{2}\right) + y \left(1 + {x}^{2}\right)$
