can you take a quick screenshot of the material and show us?

3. jagatuba

Sorry, I'm at work and got interrupted. Hmm. I'm missing something I think. -3 and 5 would be the solution to |4x|=|15+x|, but I don't see that as an answer possibility. Like jdoe said maybe a screen shot would help.

4. jazzyfa30

how do i take a screenshot

5. jagatuba

I'm not seeing a relationship between | 4x | = |15+x| and | 5 | |2y - 1|, but my math skills are a little bit rusty I'm ashamed to admit.

6. jdoe0001

usually tap the PrinsScrn or PrtSc button after the F12 key on the keyboard, then go to say Paint, and paste there

7. jagatuba

The Prt Sc button will copy the screen to the clipboard then paste that into Paint and save the file then attach that file to your response with the attach file button below your response box.

LOL Yeah what he said.

thank you for showing me that

11. jazzyfa30

i got my answer it was A

12. jagatuba

Now I'm just trying to figure out why it's |5 3| rather than 5 -3

13. jazzyfa30

i dont even know how 5 got in the answer

14. jagatuba

Well if x=5 then 4x=20 and 15+x=20 therefore 4x=15+x. Likewise if x=-3 then |4x|=|-12| or simply 12 and |15+x|=|12| or simply 12.

15. jagatuba

However, if x=3 then 4x=12 and 15+3=18, therefore |4x|≠|15+x|.

16. jazzyfa30

oh ok

17. jagatuba

Where is @mathslover when you need'm?
