Answer:
A
Step-by-step explanation:
So we have the equation: 

First, let's subtract 16 from both sides: 

Now, let's divide both sides by 3: 

Remember that with fractional exponents, we can move the denominator into the root position. Therefore: 
![(\sqrt[3]{x-4})^4=16](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx-4%7D%29%5E4%3D16)
Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!
![\sqrt[3]{x-4} =\pm 2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-4%7D%20%3D%5Cpm%202)
Cube both sides. Since we're cubing, the plus-minus stays. 

Add 4 to both sides.

So, our answer is A. 
And we're done!

Answer:
23
Step-by-step explanation:
Basically I did it backwards & opposites:
-28 divided by -7 = 4
4 + 19 = 23
I checked btw and it worked.
