I think its B but im not sure

anonymous · Answer

It's B you are right because if you put -36 and absolute value it then it becomes positive. If you absolute value a positive number it's still going to be positive.

Don't you remember my explanation from your previous problem?

Example: |5x| = 40
becomes
5x = 40 or 5x = -40
Now solve the compound equation above.
Do the same procedure to your equation.

anonymous · Answer

oh ok so it is B

mathstudent55 · Answer

Right, because the next step for this equation is
x = 36 or x = -36

Now you can try both values of x in the original equation, and you'll see that they both work.
