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

Answer 1

To solve the equation \( 3x - 3 = 6x + 18 \), follow these steps:

1. Start by isolating the variable \( x \).
2. Subtract \( 3x \) from both sides:

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

This simplifies to:

\[ -3 = 3x + 18 \]

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

\[ -3 - 18 = 3x \]

This becomes:

\[ -21 = 3x \]

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

\[ x = -7 \]

Thus, the solution is \( x = -7 \).

The correct response is: x equals negative 7.
