Let the unknown number be x . Given Two-thirds of a number is negative six.
Two third of the number x can be written as :[tex] \frac{2}{3} x [/tex]
Given this equals -6.
[tex] \frac{2}{3} x =- 6 [/tex]
To solve for x we multiply by 3 both sides
2x=-18
Dividing both sides by 2 we have:
x=-9.
The unknown number is -9.
