Given that (3m-1) x + 9 = 0 is a linear equation of one variable with respect to x, then the condition m should satisfy is m______ .

Given that (3m-1) x + 9 = 0 is a linear equation of one variable with respect to x, then the condition m should satisfy is m______ .

According to the characteristics of one variable linear equation, we get 3m-1 ≠ 0, and the solution is m ≠ 13
