Solve for x.

x3=-216 Enter your answer.

x =

On the left side of the equation, we have 3x or 3 * x. But in algebra, we usually just do 3x.

We need to find a value for x that when multiplied by - 3 equals to - 216.

We can find the value for x by dividing both sides by the coefficient of 3x. Which is 3.

3x / 3 = - 216 / 3

x = - 72

So, x is equal to - 72.
