What is the solution to
2x -8 = 2(x - 4 ) ?

also, explain how you solved it.

First, you gotta simplify. There’s really nothing to simplify so just take it out of the parenthesis.

2x-8=2x-4

Now turn the -8 into a +8. Add it on each side.

2x=2x+8

Now turn the 2x on the right into a negative. Do the same thing you did with the 8.
Now it’s:

0 = 8

That means there’s no solution.
Hope this helped :)

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
