Question

Absolute Value of H-4=9
Which solutions are right?
-13
-5
5
13

Answer 1

-5 and 13, because |13-4|->|9|=9 and |-5-4|=|-9|=9

Answer 2

So you have |H-4|=9.

Whether inside absolute value should be either 9 or -9,

So you have H-4=9 or H-4=-9

Solve for H from both equations, you will get your solution

Answer 3

First, I think you mean |h-4|=9, as "absolute value of H-4=9" would make no sense.

Remember that the absolute value operator will convert anything within the absolute value symbols to positive if that "anything" happens to be negative; if that "anything" is already positive, the absolute value operators have no effect.

Answer 4

"First, I think you mean |h-4|=9, as "absolute value of H-4=9" would make no sense."

Thank to common sense, this is pretty obvious.

Answer 5

Case 1: h-4 is already positive. Then h-4=9. h=?
Case 2: h-4 is negative. Then |h-4| has the value (-)(h-4). Solve for h.

Answer 6

@mathmale I didn't really know how to type the absolute value sign.

Answer 7

Have you found the appropriate character on your keyboard?

An alternative way to write "Absolute Value of H-4=9" would be

abs(H-4)=9.

Answer 8

This is how it was written and I really didnt understand. Oh alright I get it now

Answer 9

@mathmale

Answer 10

Oh well, then we are all wrong, since we assumed you mean |h-4|=9

Answer 11

It was my fault and I apologize for that.

Answer 12

So for this case, you just add both sides by 4, to cancel out -4 in left side of equation

then you would have |h|=9+4

Answer 13

@micahwood50: Instead of criticizing and finding fault, why not contribute something positive, something that would help the person asking the question towards finding his/her own answer?

Answer 14

umm i didn't really blame anyone, what happened recently is simply misunderstand. Nobody's fault really...

Since you are apparently expert with helping person, I think it's best if you help him instead of me, sorry.
