Solving for x is easier if
First, remove the parenthesis.

-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9

Next, group the numbers with x on the left side and the rest on the right side.

-3x + 3x = 12 - 9 - 3
0 = 0

So, x has no solution.

x-3(x-1)=3(4-x)-9=>x-3x+1=12-3x-9=>-2x+1=12-3x-9=>-3x+3x=12-9-3=>0=0
