I will give two solutions, one where everything is cubed and one where just the 3 is cubed, because I don't know what you meant.
Just the 3 is cubed solution(Which I think is correct because it has a nicer answer):
Answer:
Step-by-step explanation:
We have that .
We can subtract from both sides of the equation to get
.
We can then divide by to get
.
So, and we're done!
Everything is cubed solution:
Answer:
Step-by-step explanation:
We have that .
We can take the cube root of both sides to get .
Note that , so
.
So, we want to solve .
We can subtract from both sides to get
.
We can then divide both sides by to get
