Let's call the unknown number x. Then, your problem says, in formula language:
2/3x - 9 = 7 Add 9, both sides
2/3x = 16 Divide both sides by 2/3 (remember how to do this? You flip the fraction and multiply, like this:
2/3*3/2x = 16/1*3/2 On the left, 2/3*3/2 cancel each other out. On the right:
x = (16*3)/2= 24
Answer: x = 24
Proof: (24*2/3)-9 = 16-9 = 7 We have the correct answer.

9 - (2/3)x = 7
That's the equation, now you just solve for x.
9 - (2/3)x = 7
-(2/3)x = -2
x = 1(1/3)
(it's a fraction)
