To determine if the equation has one, none, or infinite solutions, we need to solve for x.
3(x + 2) - 6 = 3x
3x + 6 - 6 = 3x
3x = 3x
The equation simplifies to 0 = 0, which means that the equation has infinite solutions. The value of x does not matter since both sides of the equation are always equal to each other.
