Question

Use the rules of equations and inverse operations to solve the equation. In your final answer, include all of your work.

x 3 - 3 = -67

Answer 1

To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:

`x^(3) - 3 = -67`
2. You must add a 3 to both sides:

`x^(3) - 3+3 = -67+3 \\ x^(3)= -64`
3. Now, you to cube root both sides, as following:

`\sqrt[3]{ x^(3) } = \sqrt[3]{-64} \\ x=-4`
Therefore, the answer is:
`x=-4`
