Hello!

First of all, let's take away the absolute value.

x+6= 2x-1

We add one to both sides

x+7=2x

Subtract x from both sides.

x=7

Our answer is A)x=7.

I hope this helps!

With these absolute value equations, you just have to try them positive and negative or square them. We won't do any of that here.

We'll just try to solutions.  Clearly x=7 works, |7+6|=2(7)-1

-7 doesn't work

-5/3 gives a positive number on the left and a negative one on the right, nope

5/3 doesn't work either.

Choice A.
