Question: 1 / 400

Solve for x in the equation 7x + 14 = 0.

x = -2

To solve the equation \( 7x + 14 = 0 \), we first need to isolate the variable \( x \). We begin by subtracting 14 from both sides:

\[

7x + 14 - 14 = 0 - 14

\]

This simplifies to:

\[

7x = -14

\]

Next, we divide both sides of the equation by 7 to solve for \( x \):

\[

x = \frac{-14}{7}

\]

This further simplifies to:

\[

x = -2

\]

The correct answer is therefore \( x = -2 \), which means the solution indicates that when \( x \) is -2, it satisfies the original equation. This can be verified by substituting -2 back into the equation:

\[

7(-2) + 14 = -14 + 14 = 0

\]

This confirms that the solution is valid.
