Answer: ![x=\bold{\dfrac{a(c-2)}{9+b}}](https://tex.z-dn.net/?f=x%3D%5Cbold%7B%5Cdfrac%7Ba%28c-2%29%7D%7B9%2Bb%7D%7D)
<u>Step-by-step explanation:</u>
9x + 2a = ac - bx
9x = ac - bx - 2a <em>subtracted 2a from both sides</em>
9x + bx = ac - 2a <em>added bx to both sides</em>
x(9 + b) = a(c - 2) <em>factored out x from the left and a from the right</em>
<em>divided both sides by 9+b</em>
Multiplying and Dividing Exponents are very easy.
When they are multiplied, we add the exponent numbers together.
When they are divided, we subtract the exponent numbers.
In this example,
![h^{-18}* h^3](https://tex.z-dn.net/?f=h%5E%7B-18%7D%2A%20h%5E3)
/
![h^{0}](https://tex.z-dn.net/?f=%20h%5E%7B0%7D%20)
We can conclude that
![h^{0}](https://tex.z-dn.net/?f=%20h%5E%7B0%7D%20)
is 1 because,
any number to the power of 0 is 1
![\frac{ h^{-18}* h^{3} }{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20h%5E%7B-18%7D%2A%20%20h%5E%7B3%7D%20%7D%7B1%7D%20)
=
![h^{-18} * h^{3}](https://tex.z-dn.net/?f=%20h%5E%7B-18%7D%20%2A%20%20h%5E%7B3%7D%20)
take the exponents alone:
-18+3 (Because it is multiplication) =-15
Final answer
: ![h^{-15}](https://tex.z-dn.net/?f=%20h%5E%7B-15%7D%20)
