Question

Solve for x. x3=−216 Enter your answer. x =

Answer 1

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.
