Hi,

If a number(n) is increased by two-thirds of its opposite(-n), and the sum is increased by 5, the result is 10. 

Let n represent the number and -n its opposite

Write as You Read:

n + (2/3)(-n) + 5 = 10

(1/3)n = 5

  n = 15

checking our Work:

15 + (2/3)(-15) + 5 = 10

15 - 10 + 5 = 10  checks

Wish You the Best in your Studies.
