Answer 1

To solve for x, we can start by isolating the x terms on one side of the equation. We can do this by subtracting 6x from both sides and adding 3 to both sides:

3x - 3 - 6x = 6x + 18 - 6x

Simplifying this equation:

-3x - 3 = 18

Next, we can add 3 to both sides:

-3x - 3 + 3 = 18 + 3

Simplifying further:

-3x = 21

Finally, we can solve for x by dividing both sides by -3:

-3x / -3 = 21 / -3

Simplifying completely:

x = -7

Therefore, the correct answer is x = -7.
