Answer:
x = 5.2
Step-by-step explanation:
![f(x) = -5x + 11 + 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-5x%20%2B%2011%20%2B%203)
Let's first simplify our first function:
![f(x) = -5x + 11 + 3\\f(x) = -5x + 14](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-5x%20%2B%2011%20%2B%203%5C%5Cf%28x%29%20%3D%20-5x%20%2B%2014)
Now, we just need to set this function equal to our other given function.
![f(x) = -5x+14\\f(x) = -12\\-5x + 14 = -12](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-5x%2B14%5C%5Cf%28x%29%20%3D%20-12%5C%5C-5x%20%2B%2014%20%3D%20-12)
Now, we can add 12 to both sides:
![-5x + 14 + 12 = -12 + 12\\-5x + 26 = 0](https://tex.z-dn.net/?f=-5x%20%2B%2014%20%2B%2012%20%3D%20-12%20%2B%2012%5C%5C-5x%20%2B%2026%20%3D%200)
Now, add 5x to both sides:
![-5x+26 = 0\\26 = 5x\\](https://tex.z-dn.net/?f=-5x%2B26%20%3D%200%5C%5C26%20%3D%205x%5C%5C)
Finally, we'll divide both sides by 5:
![26/5 = 5x / 5\\5.2 = x\\x = 5.2](https://tex.z-dn.net/?f=26%2F5%20%3D%205x%20%2F%205%5C%5C5.2%20%3D%20x%5C%5Cx%20%3D%205.2)
