To solve for x, we need to isolate x on one side of the equation. We can do this by adding 9 to both sides of the equation:
3x - 1 + 9 = 2x - 9 + 9
3x + 8 = 2x
Now we can subtract 2x from both sides of the equation:
3x - 2x + 8 = 2x - 2x
x + 8 = 0
Finally, we can subtract 8 from both sides of the equation:
x + 8 - 8 = 0 - 8
x = -8
Therefore, x equals -8.
