Question

What is the value of x in the equation 4 (2x + 14) = 0?
9, 7, -7, -9. ​

Answer 1

x = -7

Explanation:

First step is to expand the left side of the equation. To do this, multiple 4 by each term on the inside of the paratheses.

4 * 2x = 8x

4 * 14 = 56

This gives you the equation:

8x + 56 = 0

Now, get the x term on one side by itself by subtracting 56 on both sides:

8x = -56

And solve for x by dividing both sides by 8:

x = -7
