Is the following always, sometimes, or never true? 6+8x-9=11x+14-3x

It is not always, because substitute x with any number you want. I used 4.

6+8*4-9 = 29.

11*4+14-3*4=46.

They aren't the same therefore the answer is not always.

I also did it with one through ten and none of their answers were equal to the other equations answers so never equal
