the answer is x equals negative 4
First Like terms. So -9+4 = -5 then you take -12x+24x= 12x                                              Now you have 12x-5=43 
Next your going to get ride of the -5. Add five to each side. 
             Now you have 12x=48
Then your going to divide 12 from each side
        Finely you'll have x= 4
