Answer:
x = -9/2
Step-by-step explanation:
1. Divide 9 by -1/3:
÷
=
· ![-\frac{3}{1}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B1%7D)
= -27
2. Divide both sides by 2:
2(x - 9) = -27
![\frac{2(x-9)}{2} = \frac{-27}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28x-9%29%7D%7B2%7D%20%3D%20%5Cfrac%7B-27%7D%7B2%7D)
(x - 9) = ![-\frac{27}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B27%7D%7B2%7D)
3. Add 9 to both sides:
x = ![-\frac{9}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B9%7D%7B2%7D)
(or 4.5 if you need it in decimal form)
hope this helps!
