Answer 1

@jagatuba help please

Answer 2

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

Answer 3

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.

Answer 4

how do i take a screenshot

Answer 5

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.

Answer 6

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

Answer 7

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.

Answer 8

LOL Yeah what he said.

Answer 9

thank you for showing me that

Answer 10

i got my answer it was A

Answer 11

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

Answer 12

i dont even know how 5 got in the answer

Answer 13

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.

Answer 14

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

Answer 15
