Answer 1

To solve the equation \( 3x - 3 = 6x + 18 \), we start by isolating \( x \).

1. First, let's subtract \( 3x \) from both sides of the equation:

\[ -3 = 6x - 3x + 18 \]

This simplifies to:

\[ -3 = 3x + 18 \]

2. Next, subtract \( 18 \) from both sides:

\[ -3 - 18 = 3x \]

This simplifies to:

\[ -21 = 3x \]

3. Now, divide both sides by \( 3 \):

\[ x = -7 \]

So the solution for \( x \) is \(-7\).

The correct answer is:

x = −7.
