Apologies for my mistake. You are correct. When x = 0, the expressions "x - 4/9" and "-4/9x" are not equivalent.

Substituting x = 0 into the first expression "x - 4/9", we have 0 - 4/9 = -4/9.

Substituting x = 0 into the second expression "-4/9x", we have -4/9 * 0 = 0.

Since -4/9 is not equal to 0, the expressions "x - 4/9" and "-4/9x" are not equivalent when x = 0.
