Answer:
-0.8
Step-by-step explanation:
First move the variable terms to one side of the equal sign. I always move the smallest to the largest.
![1.5a + 6 = 9a + 12 \\ - 1.5a \: \: \: \: \: \: \: \: \ \: - 1.5a](https://tex.z-dn.net/?f=1.5a%20%2B%206%20%3D%209a%20%2B%2012%20%5C%5C%20%20-%201.5a%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%20%5C%3A%20%20-%201.5a)
Solve and move the constants to opposite side. I'm going to subtract 12 from both sides.
![6 = 7.5a + 12 \\ - 12 \: \: - 12](https://tex.z-dn.net/?f=%206%20%3D%207.5a%20%2B%2012%20%5C%5C%20%20-%2012%20%5C%3A%20%20%5C%3A%20%20-%2012)
Now solve for a by dividing both sides by 7.5
![\frac{ - 6}{7.5} = \frac{7.5a}{7.5}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B%20-%206%7D%7B7.5%7D%20%20%3D%20%20%5Cfrac%7B7.5a%7D%7B7.5%7D%20)
![a = - 0.8](https://tex.z-dn.net/?f=a%20%3D%20%20-%200.8)
