Solve for x: 3x−3=6x+18.(1 point) Responses x=−6 x equals negative 6 x=9 x equals 9 x=2 x equals 2 x=−7

1 answer

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

  1. First, let's get all the terms involving \( x \) on one side and the constant terms on the other side. We can do this by subtracting \( 3x \) from both sides:

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

    This simplifies to:

    \[ -3 = 3x + 18 \]

  2. Next, we will isolate the term with \( x \) by subtracting \( 18 \) from both sides:

    \[ -3 - 18 = 3x \]

    This simplifies to:

    \[ -21 = 3x \]

  3. Now, divide both sides by \( 3 \) to solve for \( x \):

    \[ x = \frac{-21}{3} \]

    This simplifies to:

    \[ x = -7 \]

The solution is \( x = -7 \).

Therefore, the correct response is \( x = -7 \).
