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 :\(\frac{2}{3} x\)
Given this equals -6.
\(\frac{2}{3} x =- 6\)
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.
