Well, if you mean (3x-9)/(x-3) = -3x/2,
3(x - 3)/(x - 3) = -3x/2
where x - 3 ≠ 0 => x ≠ 3
Notice that x = 3 makes it undefined
3 = -3x/2
x = 3 * (-2/3)
x = -2

Presentation is incorrect and should be :-
(3x - 9) / (x - 3) = - 3x / 2_________NOTE brackets
6x - 18 = - 3x^2 + 9x
3x^2 - 3x - 18 = 0
x^2 - x - 6 = 0
[ x - 3 ] [ x + 2 ] = 0
x = 3 , x = - 2

Use parentheses. Assuming this is (3x-9)/(x-3) = (-3x)/2, x = -2. Factor out the three, cancel, multiply both sides by -(2/3). Also, don't ask the internet to do your homework.
