х4х-12/х-4помогите пожалуста безотлагательно

I didn't understand what you said cuz I am not familiar with the language but still I see an equation which can be solved.

x = (4x-12)/x-4
(x-4)(x) = (4x-12)
x-4x = 4x-12
x+12 = 8x
(x+4-2.x.4)-4=0
(x-4)=4
x-4 = 2
x = 2


If it was what was supposed to do then Please Thank it.
