Question

3x-12+3x=6+6x-17 is the equation always, sometimes, or never true?

Answer 1

The answer is Never true

Answer 2

Answer:
Never true.

———

Why?

Let’s simplify each side. Start with the left.
3x - 12 + 3x
= 6x -12

Now, let’s do the right.
6 + 6x - 17
= 6x - 11

Now, put the equations together.
6x - 12 = 6x - 11

So, you know that the equation is never true.
